But then at some point the can burst, and sprayed liquid pepsi all over the inside of my freezer! When I looked inside, it kind of looked like it had formed horizontal stalagmites on the door of the freezer, almost as though it had frozen instantly upon touching the wall or even in mid-air, which makes sense considering it would have been below the freezing point by then, and would have gotten even colder when the can burst due to the sudden expansion of the pepsi!

I would love a video on the different types of ice honestly.

[@Archimedes.5000]

Well, most substances contract when solidifying, water is the exception, and it's the reason why the phase diagram is different for it as well

[@killerbee.13]

Almost every material contracts as it freezes. Water happens to have a unusual (near-unique) combination of a relatively dense liquid phase (due to hydrogen bonds) and the least dense solid phase it can given its bond length (different crystal structures have different 'packing factors' and ice Ih is the least efficient of any of the common crystal structures, if I remember correctly), and even then the efficiency difference is quite small and ice only expands by like 10%. But other ice phases have other crystal structures (this is actually the primary way a crystal phase is defined), which I think all have higher packing factors than ice Ih. So, pretty much every other phase of ice is denser than regular ice, and I don't think there are any others that are less dense than liquid water. There are like 18 of them and I didn't check them all. There are other materials with the same crystal structure as ice Ih, but their liquid phases aren't as dense as water's so they still contract when freezing, just not by as much as some other materials. For some reason the actual packing factors of various crystal structures are incredibly difficult to find online, outside of the 5 most common crystal structures that metals and stuff have. I can't find ice Ih's packing factor at all and I've been looking for like 30 minutes. You'd think this would be a pretty basic thing, as it's a very simple geometry problem, but I can't even find the parameters I'd need to calculate it myself.

Also note that Very high pressure ice also melts at a higher temperature. For example from about 6k bar it's melting temperature starts dramatically increasing. At almost 100k bar it is frozen and that type of ice only starts melting at about 330c. More pressure and temps keep increasing for melting point. Of interest if the pressure is dropped some types of ice (formed at High pressure) at 1 atm will still have an increased melting point mildly above 0c. From memory of a documentary many Years ago it was somewhere between 3 to 7c but don't hold me to that part, but is about right I think - bit tired at the moment.

Interesting side fact: because if the low surface area with the body weight of a human, skates cause the ice bellow it to melt which is what causes you to glide so smoothly.

At atmospheric-ish pressure this should be visable from around -15°C and colder. The exposed to air top layer shrinks while the lower, exposed to water layer does not. Also the thickness of the ice should not be too much. Thicker ice is more resiliant to this dish forming effect.

This can be contained using a static warp shell. It can then be successfully repaired by hitting it with a focused inverse tachyon pulse.

Fairly low level chemistry but despite knowing the concepts (I mean, I have a degree in it...) oddly satisfying to watch. Thanks!

I got a question: If you got an object which the mass is just below the mass needed to create a black hole, you take that material and you accelerate it by like, throwing it really fast or not. *Will this material become a blackhole?*

[@Coastfog]

Since e=mc^2, yes. But no.

[@bronzejourney5784]

I like the way you think, keep being curious.

[@SlimThrull]

No. Mass doesn't increase with speed, gamma does. Here's a video explaining it very, very well: kzbin.info/www/bejne/goWtkqiXmsuHkK8 Edit: Gamma, not Lambda.

[@WanderTheNomad]

@@SlimThrull Thanks for the video 👍

[@Mr_CraftyFR]

@@SlimThrull But if you increase the speed, the material will colide with the air and it will increase it's mass if the molecule in the air sticks to the material

[@TheThinkersBible]

This is a well, "Brilliant" 🙂 explanation of a very unusual corner case in physics. Thanks for sharing!

[@Comp_Laments]

I haven’t watched it yet, but what I think would happen is that it freezes to the point where the pressure starts melting the water. Eventually reaching and equilibrium where part of the ice is frozen while the pressure keeps the other part a liquid

[@thehiddenninja3428]

Why would anyone think there was a paradox here and not simply that it'll reach equilibrium?

[@garethdean6382]

The 'Preface paradox' is a whole big thing about how a book noting that it may have errors in it is crazy. The 'Temperature paradox' is literally 'The temperature is rising. The temperature is ninety. Therefore, ninety is rising.' Paradoxes as a whole can be astoundingly dumb.

Water is like this very mystical compound that seemingly defies the laws of physics

[@Yora21]

All the way back in the late 90s, the EU did a huge study to compare the quality of school education between member countries by letting kids take a number of voluntary, non-graded exams on a wide range of subjects. I was one of the kids selected in Germany, and the one test question I remember was to write a one-page reply to the question "What would be the effects on nature if frozen water did not float?" And it's really easy to fill a page once you start going down that rabbit hole.

[@seamusriley4503]

I've been wondering this for literal years. Thank you.

[@alaskacanoe6837]

Had to stop and revisit each concept many times. it is a very good project you have done here. albiet covering many dimensions of the regelation etc. based on allowed space and pressure. As you can tell I am neither a scientist or engineer and have no formal training in such things. even the use of the graphs you use are useful... If you have time to consider, please let me ask a question about this subject. If I compress snow or ice to well over the 500 PSI needed to melt, Is is possible to keep the melted ice/water state from refreezing with a small amount of temp above 0 degree C ? lets suppose that I have a machine such as a metal shredder machine, the kind used to shred a car into small pieces, and I put snow in the shredder and let the snow be crushed and squeezed to pressures many times over 500 times atmosphere, would it be easy to not allow the regelation process with a small amount of heat? Thank you so much if you have a moment to consider.. Max..

[@mathmusicandlooks]

Keep in mind that this is under the assumption that the ice/water system is maintained at a constant temperature. There is also latent heat of fusion involved. If your container were INSULATED from any transfer of heat, then as soon as any water would freeze, it would heat up the surrounding water since crystallization is an exothermic process. That heat would transfer back into the ice, allowing it to melt again. So a thermally isolated system would undergo no phase change. Everything in this video assumed temperature constant, which would actually require you to pump heat away from the system to get it to freeze still.

[@-IE_it_yourself]

neglecting friction :D every text book does it. but good point you have to state your assumptions.

What's the difference between Gay Lussac's law and Amonton's law? I know they are ultimately the same law, but what is the historical reason why they both are the namesake of this law, depending on who you ask?

[@Clancydaenlightened]

Well if you freeze water in a hermetically sealed tube, it'll expand, but this will instead translate to a pressure increase The same way shaking a carbonated beverage causes the co2 to "expand" And at higher pressure than earth atmosphere water will freeze above 32 farhenheit Technically if you raise the pressure enough, it can freeze at room temperature. And lower the pressure it will boil at room temperature too. That's why you don't fill a water bottle full and freeze it, it will be broken in the morning

[@Clancydaenlightened]

Funny if water wasn't volatile Weather wouldn't exist, and everything would just stay wet all the time Also funny how you burn hydrogen to get water, and water is an oxidizing catalyst, and one of the the best polar solvents Yeah water is a solvent like ethanol and isopropyl But it doesn't contain carbon, so it's technically inorganic solvent You burn hydrogen and get a great universal fire retardant Only if it's not a halogen or alkali groups

[@zachb1706]

No water is different to other liquids, at higher pressures it must get colder to freeze

[@pacificostudios]

I remember studying this in college, Mostly I remember learning about the Triple Point. Water is definitely more interesting than most people think it is.

[@Damanios]

Just be careful with these experiments to not accidentally create ice 9…

[@testinhaa]

Congratulations for coming out! Non-binary water 💛💜🖤

[@Twisted_Code]

Thermal expansion isn't just the name of a Minecraft mod. Water, in particular, has a habit of both expanding and contracting over a given change in temperature (or temperature Delta, if you will), and being a pain in the posterior (well, specifically the back pants pocket) about it to anyone who owns pipes and is not a plumber. ESPECIALLY the non-plumbers, but presumably even the Mario Brothers wouldn't care for the extra unpaid work.

[@kexcz8276]

Lol. I had just completely learned phase diagrams for Steel- Fe3C, and it became obvious right away what will happen, although with iron, we can ignore the pressure because it doesn't do much with solids, thus we can use the Gibb's phase law with just +1 , but with +2 when it is water . Nice video!

[@scottylightheart7180]

awwww i’m so happy for the solidarity of freezing water in an enclosed space for coming out as non-binary i know that takes so much courage 💛💛💛

A close friend used to have the CA license plate: ICE VI. It took him 1/2 hr to explain why he chose that to me. Meanwhile I was breaking trail in the snow on our skis. Ice II, he said, doesn't occur in nature except maybe at the center of the Jovan moon Ganymede; it might have enough pressure at its core to exist there. I'll glance over III and IV. When he came to VI, it came down to having a nice looking molecular structure. Now for III and IV: Friend brought a German nuclear physicist from Munich to the US. Hermann (whom I shared a tent in the Antarctric for 3 months) made both III and IV, and I think it was III, hard to make, which had an H-bond when when perpendicular to 2 H2O molecules which forms a hexagonal plane. This bond forces these 2 water molecules apart which collapses into a different crystal structure of Ice IV. He had this awesome model hanging in his kitchen, this in the era before cel phones had cameras. Alas, years later the model broke apart. Very sad. He didn't feel like fixing it. Ice 9 like in Cat's Cradle is fiction. Real Ice IX is nothing like the fiction. Can the reader distinguish fiction from reality? Both of these friends worked at Caltech. And 1st friend was briefly (for 3 years) Feynman's boss (paid for the checks).

[@vayne06]

We were taught something like that in physics. I know that an increase in pressure decreases the water freezing point, from zero to some negative, depending on the new pressure. There's even an equation that includes temperature, pressure and volume

[@Cera_01]

Non binary water was not on my bingo list but I enjoy the idea immensely

[@hexx405]

[@abundantabsurdity7085]

Just stopped by to answer the title question without watching the video: If you stop freezing water from expanding, it will not freeze until it has adequate room to do so and then it will instantly freeze. This is why water in a 3/8 in inner diameter pipe will not break when the temps get below freezing until it literally cannot not freeze. The expansion of water will freeze and bust the pipe not at 31 but at 21 degrees or so. This is because, until the water attempting to freeze overcomes the rigidity of the pipe and busts it, it cannot freeze.

[@stroopwafelfalafel]

That’s cool! Did you eventually watch the video too?

Now listen, i was taught basic physics in school, and i know there's 3 states of matter! I dont like all these modern teachers indoctrinating my kids with liberal ideas like "non-binary ice", and 76 states of matter! Now I'm open minded, I'll call a gas a "plasma" to be polite. But we've got to stand firm that calling something Ice-3 or a Bose-Einstein condensate is mental illness! Im not paying to have my kids brainwashed with this nonsense, just so "scientists" can justify their expensive lab equipment!!! And remember Ice 1h is a slur! 1h is a slur, it's just normal Ice! Call yourself ice 3 if you like, but normal ice is just normal ice, not ice 1h!!!!!
