Cody'sLab Hi

[@thehurricane5140]

Cody'sLab Awesome to see you here Cody!

[@Grapegifter]

Actually you did make triple point, when you saw that pop in the nitrogen, what happened is you had a small ice layer form which trapped the gas, which built up pressure under the ice, and then the ice popped.

[@ekun87]

Grapegifter yes u r right.. n I'm surprised that i have to scroll through so much nonsense comments to find u..

[@AnotherDaveInTheLife]

^^^ Amen

[@prettyprairiepieces211]

If it had been a lighter blue container, you may have been able to see the ice layer.

[@NuziX3]

i was going to say the same, but i wanted to see if someone said it already

[@gertboltenmaizonave2421]

I just googled the triple point of nitrogen and it's around 100mmHg. You just passed it too fast!

[@radbrad05yt97]

Great Idea!!!!!!

[@pradiptaghosh6273]

Drey K it would lot of heat and presure than u can create at home

[@nonyabizz9390]

I can't be sure, but I think those bursts you were getting was from nitrogen solidifying, and then returning to a liquid state and boiling. Something about how very low pressure makes the freezing point, and boiling point, close to identical. I think I saw another experiment in a class room on youtube where they showed that, and that was an approximation of the reason given.

[@nonyabizz9390]

I have a feeling this will get lose under all the "put X in a vacuum chamber!" requests, especially as the video is now over half a day old, but i hope if you see this it helps. who knows, i could be half right!

[@ikocheratcr]

Yes, he got solid nitrogen in there. The bursts were caused by the thin layer of solid nitrogen breaking under the pressure of the liquid nitrogen evaporating from below.

[@nonyabizz9390]

i thought so! nice to know I'm not entirely wrong!

[@Sethcor]

YeaI was watching that too and am pretty sure it is hitting its triple point.

[@Andy-jq5yw]

pr1m3tim395 the triple point is about 26inches Hg vacuum under STP. he says on the video he only got to 22inHg vacuum, so no, it's not near the triple point. Also, you'll notice it happens early in the video while still depressurizing.

[@coolDG1]

Can't believe you didn't think this through.... you are reducing the boiling point of nitrogen so it vaporizes even more and the pump just sucks those vapor out with air from the chamber. You have to increase its freezing point for it to solidify at room temperature. You can do that by Increase the pressure, so pump air inside the chamber instead of extracting from it.

[@Nukeclearchipmunk]

No, he is totally right in this case, as the nitrogen evaporates it draws heat away from the rest of it cooling the liquid down. Eventually it would cool it so much it would freeze. He is just unable to draw enough of a vacuum to create that.

[@coolDG1]

interesting....maybe that could be the reason of that "jumping nitrogen". maybe top layer did get frozen and the nitrogen below vaporized, breaking the "ice" and spilling nitrogen. So tighter seal, more powerful vacuum and jar of nitrogen with smaller opening is needed.

[@anthonyschroeder521]

You really need a smaller opening to concentrate the heat loss. Liquid CO2 canisters are used in this fashion to easily make small amounts of dry ice. But yea, increasing the pressure would also cause bulk solidification (although at a very high pressure.)

[@drhashim1985]

Divyansh Gaba that what I was thinking about, he actually accelerated the evaporation of liquid nitrogen by depressurizing it, like if you depressurize water it will boil at lower temperature!! Doesn't make sense ha He should actually increase the pressure for the nitrogen to solidify, (that's haw the earth's core is solid iron despite extreme temperatures), I don't this can be done in his lab

[@jessanderson4180]

as the liquid nitrogen boils the remaining liquid cools, if enough evaporates the liquid can cool to below its melting point and freeze.

[@Imjaaff]

"Maybe I should use a little nitrogen to cool it down" it is genius😂

[@Timg95]

It is intriguing to see how KZbin has essentially become one huge Science lab.

[@adrian_j_jones]

You should make a silicone mould of your hand. Then make chocolate and gummy hands for your family. Like the quote "Don't bite from the hand that feeds you"

[@shernader]

wouldn't he have to keep his hand in the silicone for a day or so.

[@poseidonpwnsall]

Hydro Ococh he would have to imprint his hand on some clay or something, make a replica of his palm with that, then use the replica in the silicone

[@shernader]

+poseidonpwnsall oh ok

[@jman-nl4st]

Put bubble wrap in a vacuum chamber.

[@Energya01]

In my work with a physics show we do this on a regular basis in basically the same way. The most clear difference I see between your method and ours is that we normally use a smaller diameter glass beaker for the LN2, that may help if you decide to try this again.

[@therealDannyVasquez]

You could make a Sprengel Pump like Cody's. Keep the liquid nitrogen sealed until you have it below 1 mPa then open the nitrogen container remotely so we can see it freezing. You'll have to figure a way to open the nitrogen container remotely but I'm sure you can figure that out ;)

[@therealDannyVasquez]

+alshabaz Cody's pump wasn't built particularly well which is why it took so long. A half decent pump should evacuate in under 1 hour.

[@ScribeWolf]

but you run the risk of the nitrogen freezing inside the sprengel pump due to thermal transfer. wouldn't be as hard to as water as nitrogen specific heat is about a fourth (1.01 j/g vs 4.18 j/g) plus as you release it the nitrogen compresses (causing it to heat up, think about how when you fill a gas bottle it gets warm, but when you use it, it gets cold) cause possibly the opposite effect

[@thekanad4134]

Actually I think you should have increased pressure. Decreasing it lowers boiling point, which means it wil boil at even lower temperature. Increasing boiling point (by increasing pressure) increases boiling point, and thus melting point. At least I think so. Cuz every substance is full of energy, and air is only thing keeping a liquid particles from flying all over the place, further away from each other, becoming gas.

[@DrummanTaylor]

The Kanał :D yes, but if he's trying to make a solid, he'd want to decrease the boiling point so it would not boil away.

[@ScullyScurl]

The Idea is that by lowering the pressure and therefore making the nitrogen boil, it looses a lot of thermal energy until its cold enough to freeze.

[@DrummanTaylor]

actually, I was wrong. you would want to increase the pressure because it decreases the boiling point. Think about how the boiling point of water in the mountains is increased due to lower atmospheric pressure.

[@anugrasalaza9395]

ScullyScurl

[@myx421mjb8605]

JLTMusic Adding pressure would raise b.p. which is what you would want. Lowering pressure is the opposite of what you want to do.

[@RKSNomad]

you will need a stronger pump, or two pumps for increased evacuation. also keep the nitrogen inside the pot and keep cool lights pointed at it, as the vacuum is created it causes convection heating, making it hard to pass the triple point and create sublimation (the explosive bubbling you see). you need that sublimation to create a solid.

[@connorgarratt6573]

Hey grant great vid dude love everything u do helped me sooo much in sceince thank you

[@lancelindlelee7256]

Wait doesn't boiling point decrease as pressure decreases. That's why in a pressure cooker, there is a high pressure and also high boiling point

[@sanden7185]

Exactly He needs to increase pressure for it to work, not decrease.

[@RKSNomad]

it's the opposite, its called a critical state. as the pressure decreases, temperature drops allowing it to become solid.

[@sanden7185]

Excuse me if I misunderstand Phase Diagrams, but when a material passes the critical point (typically high pressure and temperature) it becomes a supercritical fluid, which is not a solid. Also, I highly doubt he is trying to create a supercritical fluid.

[@RKSNomad]

a super critical fluid is a critical state.... d-did you not read my comment... The critical point is where gas and liquid have the same density, creating a critical state where gas and liquid are indistinguishable... Cody's lab made a cloud in a test tube via using said fluid... High pressure creates a critical state....

[@sanden7185]

True, but only when combined with high temperature. Decreasing pressue only makes it more gasseous.

[@jeffkelly8720]

I've done it before and I used a bigger pump. It's really cool when u get to see it

[@BrianPvanOers]

You lowered the boiling point by decreasing the pressure, thus making it easier to boil

[@chrisg3258]

I just posted this before I saw your comment. I'm with you... Surely decreasing pressure is never going to encourage it to solidify. Wouldn't increased pressure be the prerequisite to encourage solidifying at a constant temperature?

[@Swithi1047]

LadyLouie I did too lol. Just decided to try again xD

[@BanilyaGorilya]

Grant looks like a 90s movie villain in those shades.

[@isnow8278]

wouldn't reducing the pressure in the vessel just push the liquid nitrogen into a gaseous phase?

[@Sal-T]

This is what I thought. Wouldn't you need to increase the pressure to get it to solidify? Lowering the pressure should lower it's boiling point, not increase it.

[@gate2soumyajit]

increasing the pressure will make it gaseous. Just like if you put pressure on ice it melts.

[@Xeroman]

Crockett_ I believe that vaccum is lowering it's boiling point, but as the air is being pumped out, the temperature drops (just like a deodorant can being depressurised). In addition the vaccum insulates the outside heat, thus making liquid nitrogen unable to solidify .

[@nitschn6871]

u should probably read some thermodynamics bro

[@Sal-T]

Soumyajit Ray ice melts under pressure because ice is less dense than water. when you go up in altitude, the boiling point of water decreases because of the lower pressure, which is why cooking times are greater at higher altitude; The temperature of boiling water is lower. in space, which is a near vacuum, water sublimates. It goes directly from a solid to a gas, since the boiling point is so low it's the same as the melting point. I think k the experiment here is to lower the boiling point to be down to the melting point, and then the boiling nitrogen bleeds off enough heat that the remaining nitrogen solidifies. I'm guessing the only way this would work is if he could create the vacuum quickly enough, and his pump isnt fast enough.

[@RayMaster_901]

[@williamcolt1073]

you could try adding some boiling chips, it should reduce the bumping that you were getting as a result of giant pockets of nitrogen erupting at once. additionally it should provide a rougher surface that would promote crystallization.

[@AwfulWildSide]

A liquid should never turn to a solid in a vacuum. By removing the atmosphere, the pressure holding the molecules in a liquid state is gone. That lets them get free and become vapor. To make a solid at room temp, pressure needs to be added. This is why one can get water to boil in a vacuum.

[@KnowHowTV]

hey grant what will happen if you put proto putty in vaccum chamber ?

[@weed9389]

nice idea

[@festerallday]

The gasket is made from proto putty. So it's already in the vacuum chamber.

[@AhurAmud]

Do I see this wrong or does not the freezing point drop with higher air pressure? Because the more air pressure, the harder can the molecules/atoms move, and the sooner they change into their solid form? The way you have done it (by lessening the pressure) you have helped the nitrogen to change into gas. Correct me if I am wrong

[@Wyzmayne01]

vacuum freezing takes advantage of saturation pressure, if you lower your pressure below the saturation pressure you start to freeze the pure substance in the vacuum.

[@AhurAmud]

So you want to say that at first it will expand but than it will solidify again? Interesting. I did not know that.

[@radjam7588]

RangerX I wonder if it would've played out differently if it was in a small closed container like a water bottle

[@AnotherDaveInTheLife]

Ah THERMODYNAMICS!! The best way to understand this experiment would be to look at the properties of Nitrogen on a Pressure v Temperature graph. You will notice that there are three distinct phases of matter (Vapor, Liquid, Solid). Now we are working in the realm of back yard science, so there is no need to explain the super-phases of matter. Anyways, in this vacuum regime we are attempting to change the phase from liquid to solid by lowering the pressure, but pretty much holding the temperature constant. Heat flow into the system is the biggest enemy here. In your system, near the end of your experiment, you notice the large burst of bubbles occasionally, this brief instant is whats known as the triple-phase of matter, unfortunately the solid turns back into vapor way too fast to appreciate it. The pump is therefore strong enough for this experiment, but you need to control the heat flow coming back into your system. Proposed Solution: immerse as much of the exterior of your vacuum chamber as you can into a slightly bigger container of liquid nitrogen. Lowering the heat-flow intake or making that heat flow negative will definitely improve your results. Thank you for reading!

[@Skelath]

Or just reduce the size of the vacuum chamber.

[@davidwilkerson1904]

I might have a suggestion for this experiment. Could you try putting several vacuum pumps in parallel with each other to draw off the one container? The theory being that it would distribute the workload and either reach your goal quicker or keep the individual pumps cooler (hopefully both.) 4 pumps seem to be a nice round number.

[@xapemanx]

umm, reducing atmospheric pressure lowers the boiling point, you were basically making it easier for the liquid nitrogen to vaporize

[@samueljames9342]

Vacuum pump was way too small for that application, I use to work at an investment casting place where all castings were poured in a vacuum chamber. They could pump a 30 cubic foot chamber down into the micron range in less then 30 seconds. Any liquid placed in the chamber would freeze in less then 15 seconds. The problem with liquids in a vacuum system is contamination, it could take up to an hour of hard vacuum ( 10 to 20 microns) to remove all the moisture from the oils.

[@madisonking8057]

wait whaaat do'nt things boil off and become more gaseous/less solid under low pressure

[@madisonking8057]

simce when do heat and pressure not vary directly

[@malcanth3481]

madison king Yes they do, but as more liquid boils, more energy is removed from the liquid. Once enough heat is removed, the remaining liquid will freeze. This is the same way water can freeze in a vacuum.

[@hoganszumski1261]

eventually as you decrease the pressure it reaches the triple point at which it can exist as a solid, liquid, and gas at the same time

[@SuperVALERock]

Cody'sLab did a great video on this; Water under vacuum will eventually boil, but if you keep the vacuum going it'll eventually boil itself into freezing. Strange, I know.

[@tOSdude]

Boiling is an endothermic process. The nitrogen that boils away takes the heat of the rest of the nitrogen as it goes. Eventually the nitrogen that is left will reach its freezing point.

[@Tizzandor]

how about you try and build a 2 stage vacuumchamber.. like there are 2 cans, a big and a small one, the small one is connected to the big one and the big one is connected to the vacuum pump, both seperated by valves. so if you use the pump, you can make a vacuum in the bigger container and use this vacuum to rapidly make a vacuum in the smaller one by opening the valve that connects the two maybe this could be the solution why the liquid nitrogen didn't turn solid, but this is just a theory based on nothing also i'm sure that the rapid vacuum would make a cool effect on water bottles or marshmallows since they would expand so fast instead of the slow and equal expansion with the vacuum pump only

[@malcanth3481]

Tizzandor Because the smaller chamber would be at one ATM of pressure, there would not be even close to a vacuum by opening the small chamber to the large one. It would lose a lot of pressure, but it wouldn't be any better than using a pump to remove that same amount of pressure. It is easy for a pump to remove the majority of the pressure, it only becomes difficult for the pump once the pressure is greatly reduced. A large vacuum chamber wouldn't make the small chamber a vacuum, it would only equalize the pressure between the two.

[@akkupackage]

melting point drops at low pressure? something seems wrong to me

[@this_mfr]

Cause it is wrong. He totally screwed this one up and flip-flopped it. Decreased pressure = decreased boiling point AND freezing point, meaning he would have had to decrease the temperature. I really don't understand how he didn't comprehend this. If he knows decreasing the pressure decreases the boiling point, as evidenced by the boiling off of the liquid, why in the world did he think it would freeze? To increase freezing point, you should increase pressure. Just like a can of pressurized air. The air liquefies at higher pressure, therefore it would also freeze at even higher pressures.

[@juergenhaessinger4518]

The triple point of Nitrogen is at 0.124 Atm @ -209.97°C so lowering the pressure is a requirement.

[@Kindyno]

he also poured nitrogen on a "hot" engine to cool it. so there is that.

[@DavidKenny64]

Just because one doesn't understand it, doesn't mean it's wrong. Decreasing the pressure lowers the boiling point. The liquid is a mixture of molecules of varying energy levels, the temperature is basically the average of the energy levels. With the lower pressure, the most energetic of those molecules are able to escape the liquid leaving behind the lower energy molecules, resulting in a lower temperature liquid. He did start the process all over each time he had to add more (warmer) liquid nitrogen to the pot.

[@jariroth]

He was correct in saying that the boiling point would drop at low pressure. But he understood it incorrectly, at low pressure it boils more furiously at room temperature. You need higher pressure for it to solidify at room temperature. You can think that high pressure is pushing the molecules closer to each other, which is the solid state, and vacuum is pulling the molecules further apart, which is the gaseous state. Also, as you raise the pressure and the molecules get closer together, the heat energy that is stored in them gets released to the surroundings. Its the opposite with low pressure, for example if you release a gas thats under high pressure back into normal pressure, it absords heat at the point where it expands.

What happen if you mix lava with liquid nitrogen

[@Barondross]

ZzDanishzZ that would cause molten rock to splatter and thays very dangerous but other than that nothing would happen really other than some of it slightly cooling down.

[@petar.pandza]

ZzDanishzZ omg yes but it would be tough to do

[@Aetheriaa]

Noter It's either leidenfrost effect or that

[@eclairchat]

ZzDanishzZ where will you get lava?

[@ZzDanishzZ]

Fun Time At volcano or somewhere else

[@Xeno4700]

Make gummy king of random's logo!

[@Xeno4700]

Do it!

[@a-lphaofzeldaformegaming7907]

yes; agreed

[@Xeno4700]

Help me i want grant to notice this ;)

[@junewong9225]

Xeno 4700 Grant! Please do it,it sounds cool!!!

[@dhruve_]

Xeno 4700 yes yes yes

[@Brozza]

How about, how does dry ice react in a vacuum chamber?

[@matthewchung1411]

Double Clutch Gaming hi

[@Brozza]

heyyy

[@Nblockley64]

Hey Grant, try toothpaste, shaving cream, whipped cream, a doughnut, and proto-putty in a vacuum chamber!

[@mr.moeslegos7453]

How about you put jello in the vacuum chamber? If he'd already done this can I have a link?

[@mr.moeslegos7453]

Or maybe magnetic ferrofluid?

[@zappuccino2202]

Mr. Moe's Legos yes! We need him to do magnetic ferrofluid, if you don't know what that is... then it's magnetic liquid

[@parthhiren4419]

Will sodium metal explode or freeze in liquid nitrogen? should give it a shot!

[@Avariel]

It wouldf just cool as nitrogen is generally non reactive. It's the water that causes Sodium to explode as it produces hydrogen gas by turning the sodium and water into sodium hydroxide. Na + H2O = NaOH + H + Energy.

[@malcanth3481]

N7SpectreLT It actually isn't the production of hydrogen that causes the explosion. It is a coulombic explosion due to the sodium violently ripping itself apart as the 3S electron is pulled to the outside of the metal to bond with OH ions. The explosion sodium causes is much too large to be just as a result of the expansion and ignition of hydrogen gas.

[@malcanth3481]

Parth Hiren Just so you know, sodium metal is already frozen. If it is a solid, it is frozen. Things don't need to be cold to be frozen.

[@Avariel]

Malcanth That's pretty interesting. Thanks for the correction =3

[@parthhiren4419]

Oh Yea! Thanks Guys!

[@elisewilson7567]

can you see what happens when you oobleck in a vacuum chamber.

[@cubeworm7657]

Elise Wilson yes

[@arlaken]

The small bursts that you saw on the first try, was actually the the liquid nitrogen forming a thin solid sheet above the surface but due to the pressure building underneath it was broken creating a mini explosion.

[@JLchevz]

you need more pressure to solidify something not less pressure, put un sure you already knew that

[@wobeck]

No, not pressure. To solidify nitrogen, you have to lower its temperature from -321°F to -346°F. You have to freeze it. Increasing pressure would heat it. To freeze it, you have to reduce pressure.

[@teratogenus]

wow nice understanding of physics!

[@JLchevz]

But increasing pressure also increases the freezing point

[@Spaceizcool]

Changing pressure has nothing to do with temperature...

[@antonhelsgaun]

By decreasing the pressure of the chamber it will make the nitrogen boil faster which lowers the temprature

[@panickedwatermelon4648]

What happen when you put a balloon filled with helium into a vacuum chamber

[@mohammedalnayar]

Back I think in 2010, when Felix broke a record in free fall.. the pod that he was in was actually lifted with a balloon.. and as it was getting higher and higher, less atmospheric pressure were surrounding it, and it started expanding. This was my theory about what happened (didn't research it at all), so I'm interested in knowing if it's true or not XD

[@Ixs4i]

yeah thats pretty much exactly the case forgot exactly why but its because that the balloon is in a vacuum that it expands in that way

[@renuuzra9044]

How does Molten Bismuth react in Liquid Nitrogen?

[@turf8999]

Taha Menouni It would solidify. What did you think would happen?

[@renuuzra9044]

BlerZer - GD Do you know about Bismuth crystals?! I was wondering if there shape will change and if they will be made faster and if it will make a difference since Bismuth has a very low melt-point! And no I'm not doing it for the 25$ if your wondering😒 and I just gave you the reason why I commented this

[@BuriousBorge]

Hey it's me Jtrz, I was first on your livestream on insta!

[@gdhddbhx3363]

deep fry dry ice

[@thesmallpotatothatcould7261]

Yes! Yes!

[@bobyantzer2513]

yeah!!!!!

[@PvtNix]

Try using a sponge soaked in liquid nitrogen in the vacuum chamber

[@animalfunnyclips1828]

Please put proto putty in liquid nitrogen

[@JakeCarley]

I'm pretty sure to make solid nitrogen you have to pressurise the air, also you're not changing the temperature just the point which it boils or freezes. The way it works is the water molecules have the air pushing against it, when water is heated it has the energy to counteract that pressure and turn to vapour, by removing the air you make it easier for that water to overcome the affect of the air. So by applying a vacuum to the liquid nitrogen you actually helped it evaporate quicker

[@sillyslayer_]

do a video explaining "inches of mercury "

[@jaunjansenvanrensburg5100]

I saw someone comment this I feel bad for them not gettting 25$

[@kamakazedragongaming3129]

Clorox Bleach that was me.. heheh

[@austinbazinet6788]

Clorox Bleach maybe he was unable to contact him or her

[@kamakazedragongaming3129]

I am clearly able to contact.. Heheh

[@alexvilla6217]

Clorox Bleach alot of people commented this idea, im guessing thats why he didnt give anyone $25

[@QuAdDaStuD]

Clorox Bleach It was me :(

[@christiancabello9605]

You should put liquid nitrogen frozen goo in the vacuum chamber, and I love your vids.

[@snackrificialduck]

Coconut in the vacuum chamber

[@shelleyyuan24]

what happens if you put jello into the vacuum chamber?

[@MattGreenhill]

What would even happen if you put mercury in the vacuum?

[@kaouiii]

Matt Green nothing

[@MattGreenhill]

DaBeanLord You forgot to keep in mind the change of pressure, and that the oxygen would be sucked out.

[@brink1551]

Matt Green im pretty sure he knows what a vacuum does

[@MattGreenhill]

DaBeanLord Atomic properties Oxidation states 2 (mercuric), 1 (mercurous), −2 ​(a mildly basic oxide)

[@kaouiii]

Now that I think about it, that's true.
