Does Water Really Boil in a Vacuum Chamber? And Why?

[@eelueelu9069]

I was studying physical equilibrium in chemistry and I was reading about what is boiling point(Temperature at which vapor pressure of liquid become equal to external pressure). Then I thought that if the external pressure is reduced then the boiling point will also be reduced and then I searched on KZbin what will happens when we boil water in vaccum and then this masterpiece video came to me. Thank you very much bro. You always give me practical knowledge of physics and chemistry.

[@noahway13]

So how does heat boil water?

[@noahway13]

When easing pressure like he did, it does not produce steam? I didn't see steam/condensation on glass.

[@youtubegoldmines]

It can be studied interestingly considering H2o gas and H2o liquid in equilibrium. And then apply le chatliers principles

[@Neoprenesiren]

@@noahway13 It gives the water enough energy to overcome the pressure of the air. Allowing it to basically jump out of it's liquid state. It's the difference between jumping on the moon and earth. You can get better results in once place with less effort, but you can still achieve the same effect with more energy if you really wanted to.

[@cnbaburaj]

This is what called "INFORMATIVE SOURCES" on the internet. This experiments really help finish my doubts faster and better.

[@Tact012]

At a lower atmospheric pressure, there's less force pushing down on the surface of the liquid meaning the energy threshold to jump from liquid to gas is lower. Since it requires less energy to become a vapour it can boil at a lower temperature -- or room temperature (temperature is simply the average kinetic energy of atoms in a substance)

[@XwpisONOMA]

Not accurate, have you wondered though why you can't cook (boil) an egg in this water? Bubbles forming when you boil water to cook ...pasta and bubbles forming in this experiment are one and the same: Gas molecules forming and escaping from the water. The difference is the method used. One is the introduction of energy (heat) and the other is reducing the atmospheric pressure around the water. Think why it is recommended to add salt in the pot for cooking: Because it helps the water reach the recommended higher energy point (e.g. at least or a bit higher than 100C) and faster. Bottom line is you cannot boil (cook) hard boiled eggs in this kind of vacuum environment. so you guys should stop saying, boiling. It is not!

[@Tact012]

@@XwpisONOMA Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. Wikipedia It's literally boiling.

@@XwpisONOMA so boiling is defined by the ability to cook an egg in a liquid? Hmmmm

[@YellowBoi]

@@XwpisONOMA Cooking an egg is caused by the denaturation of proteins inside the egg. All proteins denature at a high enough heat. As the proteins denature, they permanently change shape, although an egg has been "un-boiled" in a Nobel Prize winning experiment in 2015. Boiling water is fundamentally different to boiling an egg. Boiling water changes the state of the water, and boiling an egg denatures the proteins inside the egg. Hope this helps :)

[@spruce_goose5169]

1:22 Your explanation for boiling isn't 'wrong' per-se, but it's incomplete. What you describe fits the definition of 'evaporation' better than boiling. Boiling is when the vapor pressure of the liquid (which changes with temperature) exceeds the pressure exerted on the liquid by the surrounding atmosphere. This helps to explain why reducing pressure can induce boiling without changing the temperature (reduction in external pressure-no change in internal vapor pressure). It also explains why raising the temperature, as is more traditionally done, causes boiling (no change in external pressure, but a rise in internal 'vapor pressure' of the liquid).

[@absolutezero6733]

Genius. It all makes perfect sense now.

[@Scrungge]

Do you know if the bubbles in the water (the air dissolved in the water) are also just pure nitrogen molecules? Or do the nitrogen and oxygen molecules always stay close to eachother to form air (the bubbles)). Hope I'm clear ineough :)

@@Scrungge Hi Berton. I'm not clear on if you are asking a question related to my post? The 'air bubbles' in boiling water are actually water vapor gas bubbles, not 'air' at all.

Why is the surrounding glass is cooler? When water heats up and boils, it takes in energy to overcome intermolecular forces of attraction between each H2O molecule, thus turning into a gaseous state. This is also called an endothermic reaction. (Takes in energy) In this case, since there is no constant supply of heat energy supplied, they will absorb energy from its surroundings to break the bonds, causing the surrounding glass panels to cool.

[@josephmitra6092]

The key here is pressure is directly proportional to temperature, if you the reduce the pressure as in vacuumed space you also reduce the temperature or the boiling point of a liquid. As shown the container with liquid inside is vacuumed there by reducing the press\temp, so the temperature around area of the glass container no matter how low it is will be absorbed by the liquid in the glass and cause to boil. Same principle is applied in refrigeration.

Ithachi Uchiha I've heard this claim before. Why exactly would the water immediately freeze?? Is there a video of this somewhere?

[@lial4357]

DANG JOS it will freeze because its below 0°C it just doesnt freeze while in the vacuum chamber because changing the pressure decreases the point at which it does so (just like it decreases the temperature needed to boil)

[@DANGJOS]

+Lars L Lowering the pressure over water actually increases its melting temperature; it doesn't decrease it. I would question the accuracy of his thermometer. Even if the thermometer is accurate, the most likely reason for the lack of freezing is super cooling. Not a reduction of pressure. The triple point of water is actually at 0.01 C

[@seehams2643]

looking at the triple point graph of water, increase in melting temperature while lowering pressure only happens at 212.9 MPa until 10MPa, the rest of the pressure is opposite of what you said. Triple point only means at that pressure all 3 states of that matter can exist together. I would not question that thermometer, it is only a matter of time that the water turns into solid/gas because the pressure definately are below the triple point of water due the the temerature kept decrease in the water, at one point the temperature surely will stop and that will be when the freezing happens. @DANG JOS you should take a good look at the graph seriously...

[@CinderellaCostallas]

This was the most interesting I've seen so far from this channel

[@GiGaSzS]

One question in the end, when temperature of water reached freezing at normal pressure. Would the water freeze instantly if you would open vacuum chamber or would the temperature of water rise?

[@empyrionin]

Neither. The temperature decreases because it boils. That means that for it to increase it would have to undergo the reverse process. When you open the chamber it does, and it condensates, but on the walls, no contact with the water, so the heat doesn't go back in. Plus, most of the vapour which extracted the heat in the first place was taken out by the pump as it tried to maintain a vacuum. Freezing also needs a nucleus. So unless you tap on the glass, it wouldn't freeze in normal pressure either at sub zero temperatures.

[@garfielf_e]

@@empyrionin Where does the water vapour actually go whilst the vacuum chamber is on?

[@dominadorcordova2280]

i see.. so this just added to my understanding of what happens on air separation system of oxygen, argon and nitrogen. although it doesn't technically like the vacuum chamber, like the opposite way since it compressed the air to higher pressure and not suck it out, the boiling part was the same to the way it form just the fog then the watery fog it produce was the high purity liquid oxygen. Imagine at negative degree it says boiling point? So its not about the heat, but the state it starts to evaporate.. thank you for this experiment and it enlighthen me on the field of work I was on.

[@MrKULVIS]

this is the same concept that compressed cans of air use, the liquid boils forcing the air out and also is why the can cools so rapidly

[@dyeus4464]

Kulvis Flabu when we use compressed can (paint/ butane) the contents are actually decompressing, isn’t it? So I think the cooling effect can be attributed more to the movement of the propellant’s molecule rather than the boiling of actual liquid content. Same concept with refrigerants in aircons and refs. Or are these all the same principles?

Since the majority of mass of the vacuum chamber is the solid walls of the container, removing the air from inside will not noticeably change its weight.

The Action Lab way late to the game on this, but "normal" pressure in this case wouldn't be the same as on land. Keep in mind, you're under water, so you're under a lot of pressure.

As I learned from a physics professor once, the internal pressure of a steam bubble is equal to the vapor pressure, and if that is smaller than the outside pressure, then the bubble will literally collapse back into the liquid. This is why, when you put water on a hot stove, you see water on the bottom get hot enough to form a bubble, but it collapses before reaching the top. This is of course because the water isn't yet hot enough to sustain the steam bubbles

[@studentofscience]

the pressure will increase just enough to stop the boiling effect, yes you have to keep pulling vacuum. the water will turn to ice with a good vacuum pump. you can also heat up a bottle of water to boiling point then take it off the flames put a cork stopper. the water will stop boiling after a short time but by placing your hand on the bottle it will start to boil again. this is because you remove heat from the trapped air and it creates a vacuum in the bottle and the water boils.

Boiling occurs whenever the vapor pressure of the liquid and the environment pressure are equal. Evaporation occurs at all temperatures between the melting point and the boiling point, (fastest evaporation speed at boiling point)

[@stanleymeyer9936]

It's called, "sublimation," which means it becomes gas but temperature always remains the same.

[@yzbrian]

That's not what sublimation means. Sublimation means that something goes from the solid phase to the gas phase without ever being in the solid phase that usually is in between.

Could you cook soup with the boiling water in the vacuum

[@neil758]

why say "boiling"? it doesnt heat up! should be called "bubbling"

[@TheActionLab]

+Neil Baxter because the definition of boiling is when the vapor pressure of the liquid is greater than the pressure surrounding the liquid. Bubbling is when there are simply bubbles of a gas in a liquid. Boiling and bubbling are completely different phenomenon.

[@BloodiusAurion]

Water in a vacuum first bubbles then boils!

[@CPThomasam]

Felix Rojas That's because some parts starts boiling first

[@rfelton77]

So little bubbles aren't boiling but big bubbles are?

Are there any water purifiers that get the dissolved air out of water? Because it makes my ice taste bad.

[@DJAsHeRMusic]

The dead sea is lower than sea level so does water need to be at like 102c to boil?. My mum has been there and says it's really strange but cool and things happen that don't anywhere else. Floating on the high salt water and not being able to be sun burned at all also even tho it's like 40c air temp you don't sweat much like you would in the UK at anything 25c+ . Would love to go there.

[@andreasgeorgilidakis]

The boiling point of the dead sea is most definitely higher than the 102C that you mention. Not just because it's more than 400m below sea level (so the pressure is actually higher there), but also because the hypersaline water has an even higher boiling point due to the salt which is dissolved in it (so even at sea level, it would be higher than 100C degrees).

[@lopamudraray8123]

Boiling is associated with heating...just a question...regarding this another obseration might be that due to reduction in pressure the air molecules in the water escape at high frequency which feels like water boiling....so mightbe that the water thatis looking like its boiling is actually air leaving it fast...so the residual water which is now low in air is cooler...

[@suyashishan1960]

Love your videos, bro

[@nekogod]

Seems very logical. If you use a pressure cooker water boils at a higher temperature. So if an increase in pressure increases the boiling temp then a decrease should decrease the boiling temp.

[@teamwork1008]

If the chamber volume is small enough, and we've reached a vacuum pressure where the water is boiling and we are maintaining that pressure (we are not further reducing the pressure) doesn't the partial pressure of the water vapour reach its 100% relative humidity (saturation vapour pressure) and suppress the boiling phenomenon ?

[@Term-0]

Boiling doesn't rely on gas to take up the liquid. Normal evaporation and boiling are 2 different things. When boiling, the liquid does not need to diffuse into a gas, but directly becomes gas. I would say that a lot of traditional 'boiling' like on a stove is just evaporation and not just boiling.

[@sharkunmoba3706]

So pressure diffrence also changes waters freezing point.

[@zeendaniels5809]

Yep. That's how pressure cookers work.

[@pandakso3365]

Cool! Next time my city puts a boil water notice I'm going to put my tap water under vacuum pressure to do it B)

[@MrWvid]

What a good toast at the begining. Cheers

[@jhendricks448]

Can you put a small open bottle of water in the vacuum chamber and see if you can freeze it? Even if It doesn't freeze without you "agitating" the water.

[@Ru4444]

Very informative, thank u.

[@adamoshea2793]

When the gases boil of from the water is there a way to collect the oxygen

[@markhutchins3643]

When you open the valve and release the vacuum by adding air, does that air dissolve back into the water?

[@locky2562]

Is it not dangerous to put a battery in a vacuum chamber? Especially one of the sealed button types?

[@PeterPete]

Have to cover this in my next upload!! Great action!!

[@fredamber8238]

Interesting. That would be roughly the situation on Mars. The atmospheric pressure on the red planet is so low that water boils. Basically one could say that the atmosphere of Mars is rather a bad vacuum.

[@bmeetze]

What about putting actual heat boiled water in your vacuum chamber? That would be cool to see.
