    @uncleeddy1234 actually, what happens is that if the pressure remains constant (notice the bottle squeezed inward), no matter how cold it gets, it remains the same state. when that is disturbed, pressure changes, and thus causing the water to change state. (im a chemistry student)

    @SeannyOConnor because as the cooling mechanism turns on and off, it raises and lowers the pressure inside. also, when someone opens it, the pressure changes..

    It's carbonated water left in a freezer until it's nearly frozen. I don't know the exact details, but shaking it freezes it.

    @extremepietbh (Obviously simplified) When water freezes the molecules get stuck together. (Allowing it to freeze) But when you add carbon to the water it gets in the way of all of the molecules sticking together. (Therefor the water can not freeze.) By opening up the bottle you release the carbon, thus allowing the molecules to stick together. (And they are already at the freezing point which is why they stick together so quickly.)

    @tHeMeTaLmAnIaM I call shenanigans. When making ice in a freezer, the water is only exposed to ~1 atm (you know, standard atmospheric pressure). The pressure never changes, and yet ice is formed.

    @livexthexlife192 Could you clear things up for me, so the water is "cold", how "cold" specifically at what temp can this happen? And this "something cold" has to be lower by how many degrees? Is it because the transfer of energy (The "heat" from water to "something cold")?

    It is not carbonated water or some special fluid. I've done this many times and i think the way it works is since the water is purified there is nothing for the ice crystals to form on so i can get below 32 without forming crystals. When you shake it bubbles are formed allowing crystals to form.

    Water is an odd substance in that it expands when freezing. Most substances become denser. In order for water to freeze, it must expand, and if the container is strong enough, it will prevent the water from freezing. Pressure = liquid water, while pressure usually = solid everything else.

  • @tHeMeTaLmAnIaM
    @tHeMeTaLmAnIaM12 жыл бұрын

    @SeannyOConnor no no no, i am contradicting your claim, because in that bottle, the pressure would have been constant, and in a freezer, the pressure is not constant.

    @uncleeddy1234 all I learned in chemistry was that Pure H20 has a freezing point below 32 degrees.. snow flakes form because of impurities in the water.. although i dont know how to tie this point in with your water bottle as it looks like it has been opened.

    just watched this video in my atmospheric sciences class. this is due to something called supercooled water, water can remain liquid below freezing but it turns to ice when in contact with something cold.

    That is false. Supercooled water turns to solid form when disrupted by a sudden force.

    If there's no nucleation sites, it's possible to supercool the liquid well below the freezing temp.

    I tried to make a supercooled water video, but it didn’t go as I planned. I had a bottle of water stored outside for many hours with temperatures dropping to around 25 degrees Fahrenheit, and I gave the bottle of water a good shake 3 times. It stayed liquid. When I took everything inside the water started to freeze, and 30 seconds later I looked and the water in the bottle was frozen. I was shocked. Does anyone know why this happened?

    Its not carbonated water, "hot ice," or magic, as many of you believe. This is just a normal bottle of water that happened to stay liquid below 32 degrees F. Not that hard to do, really. Its actually pretty common in clouds. And freezing rain? Yeah. That's supercooled water too. And as for everyone making fun of him for not knowing the month, give the guy a break. He sounds a little exhausted. And I'm sure you've screwed something up worse than that before.
