      @MechanicalDoll Před 7 lety +33

      Sadly not enough on youtube, i mostly see americans only use the imperial, which is no problem, but if they dont even "translate" it to the metric it is kind of insulting.

      Americans don't use the imperial system. They use the English system which is not the same as the imperial system used in England before it went mostly metric.

    • @theduder2617
      @theduder2617 Před 6 lety +1

      Excellent inquiry! But be aware, I SUCK as a teacher. And what I leave here as a response, I advise anyone curious to check on it. If I am wrong, I will acknowledge my error and make efforts to correct the error(s).
      Since the chamber is already at it's maximum vacuum (or at least close), turning off the pump will cause the boiling action to slow down with time.
      Assuming the chamber has no leaks, the water will continue to boil and cool until the escaping water molecules equalize the vacuum in the chamber.
      The vacuum will not equalize completely. But enough to slow and eventually stop the reaction, and eventually the water remaining will return to the ambient temperature of the chamber.
      But his moisture absorbing powders inside might end up absorbing all of the water in the glass if left in the chamber for a time period.
      The pump must remain running in order to maintain the vacuum needed for this experiment to do what it is doing. Remember, that water is not just boiling. It is also "evaporating", or achieving vaporization as it boils. The same as on your stove top.
      And is why he added the moisture protection to his chamber. The water molecules will attack the piston wall of the pump, lowering it's ability to pump air, if it does not do more damage that is.
      (The only reason for the temperature drop in this experiment is due to the fact that the water is evaporating, or "vaporization" to be technical.
      It's the same idea behind the fact that sweating aids in cooling our body.
      Without the vaporization, temperature will not lower without external forces. (air conditioning, freezers).
      And when the vacuum stops, so will the vaporization process. Usually takes a full 3-5 minutes depending on the power of your vacuum chamber for the process to slow to a stop. (+/- several minutes)
      ALL THE ABOVE BASED ON USING ONLY WATER IN THE GLASS WITHOUT ANY ADDITIVES SUCH AS IN THIS VIDEO

      Yasin Omidi the amount makes the poisons and the medicines. Many poisons are used in lower amounts as medicine eg curare in surgery. Hell many fruits have cyanide or cyanide like compounds so all of us have eaten cyanide most likely at some point

    • @jennali9800
      @jennali9800 Před 6 lety +1

      +Eagle 367 Pretty sure you're thinking of the fruit pits (apple seeds, peach pits, etc.). Also the phrase is "the dose makes the poison," I think you just quoted a song right there ("The Difference Between Poison and Medicine is the Dose" google it). But otherwise you're right.
      Plus, not all cyanide compounds are dangerous. Cyanocobalamine is a cyanide compound, and it's better known as vitamin b12. (This is why hydroxycobalamine is used as an antidote in France; it binds with the cyanide group in, say, hydrogen cyanide, and forms b12 instead). Prussian Blue is still commonly used as a blue pigment (that's why it's called Prussian *Blue*, not Prussian Pink or something) and (as Cody mentioned in a different video) is used as an antidote to thallium.

      I heard of a planet that was discovered (the Thoughty2 video about 10 strange planets), that mostly consists of water and in a depth of X km under the surface the pressure forces the water to become ice, while the temperature is around 600°C or so. The ice is called ice X (ten) and is probably as hard as rock (sry if these information are not accurate it's a while since I watched it)

    We used to do something similar to this, though it never froze for us. We used to seal water inside a glass jar and turn upside down. Then we would put ice on the top, this would cause a drop in pressure and the water to boil. Just an odd thing we used to do.

      Nicholi Martin the ice cube made the air shrink enough for the dissolved oxygen In the water to come out and regulate the pressure but in this the air came out to regulate the pressure and got sucked out making there no barrier I guess and the water froze

    • @nicholi8933
      @nicholi8933 Před 7 lety +3

      It did pull the oxygen out, but if you have enough room in the jar with enough water you can still get it to boil, just not freeze. I just thought I would mention something fun I did years ago for my nieces.

    • @jason200912
      @jason200912 Před 7 lety

      Hey I don't understand why the drop In pressure in the video caused the water to freeze. With looser bonds, the molecules should be more active and be able to boil more. So why did the drop in pressure cause the water to freeze? It's been about 6 years since I last took chemistry

    • @nicholi8933
      @nicholi8933 Před 7 lety +1

      The boiling point just means the energy it takes to go from the liquid phase to the gas phase. Since the more energetic molecules are going into the gas phase, the remaining are of a lower temperature. That is basically why.

    • @garethdean6382
      @garethdean6382 Před 7 lety +26

      That depends, in a small enough volume you can't *fit* an atom, the lower the pressure the less likely any given volume is to contain anything at all. In the lab it's possible to make milliliter perfect vacuums easily enough.

    • @hanswoast7
      @hanswoast7 Před 7 lety +12

      Mostly you just classify the kind of vacuum by the pressure left (normal, high, ulta high, etc.). So in a classical setup you will mostly just say it has a strong vacuum with 10^-9 bar or so. But if you try to push the limits with like very small volumes, you might crack the usefulness of the difinition of vacuum. Even if you manage to get out all gas and other real particles, you end up with vacuum fluctuations and thus virtual particles (quantum mechanics) which are basically pairs of matter and anti-matter popping in and out of existence. Those are always there and also can do work (see casimir effect), even though you classically (newton mechanics, thermodynamics) have a perfect vacuum. So if you try to be precise you have to check definitions and their purpose. I hope that helped^^

    This was pretty interesting! I don't know why it never occurred to me that water would behave this way. I would have assumed that the water would just boil off until it was gone. It works just like the refrigerant in an air-conditioner or fridge. Only instead of compressing a gas to make liquid, you're depressurizing a liquid so it gases off... AND FREEZES. Fascinating!

  • @titaniumsandwedge
    @titaniumsandwedge Před 7 lety +10

    The freezing phenomenon is quite common and is easily anticipated. The overarching relationship is the vapor pressure curve. If at a certain temperature and pressure, liquid water should be a vapor, the liquid will suck energy out of the water to vaporize. The huge latent heat of water causes the water temperature to drop. But the vacuum continues to go down so the steady suckage of energy continues until the water is frozen. Then sublimation takes over.
    Most liquids exhibit this phenomenon. But water has the highest latent heat of vaporization so the effect is more dramatic.
    I am most glad that this experiment does not involve mercury. One day you may get madder than a hatter.

      @taylorwestmore4664 Před 6 lety +1

      Your explanation is not wrong, but you some funny language that convolutes the thermodynamics a bit. Maybe I can restate your point so they understand.
      The process of water boiling is exothermic, it requires water molecules with enough kinetic energy to leave the bulk water and surface tension layer. Since temperature is just the average kinetic energy of water molecules, the fastest moving molecules will boil first, leaving the remaining water with a net loss of kinetic energy so that it's average temperature is now low enough to freeze.

    Hi Cody, In a previous video you mentioned that mercury has a vapor pressure as well, since it too is a liquid, although much lower than water. Would you be able to boil liquid mercury in a similar setup to this one? And eventually get to solid mercury?

    • @theCodyReeder
      @theCodyReeder  Před 7 lety +26

      For that I would really have to put it in space since the vapor pressure at the triple point is something like 10^-12 torr. But yes it would be possible.

    I've had this water / pressure question since I took physics in high school. If you had a pressure chamber capable of increasing the pressure inside above 784 times that of atmospheric pressure would there be a point where water becomes buoyant due to it's inability to compress significantly and it's density would be less than that of the surrounding air?!

    • @nitrodasnipaz9392
      @nitrodasnipaz9392 Před 7 lety +5

      This really made me wonder, In theory I think you would be able to, It would just be a challenge to make such a high pressure chamber along with some unexpected side effect that I'm sure would pop up. It would definitely look interesting though.

    • @fleshtonegolem

    • @tinymarshable
      @tinymarshable Před 7 lety +15

      Substances have a critical pressure and temperature, which after that T and P are reached, the substance will be a supercritical fluid and exhibit properties of both liquid and gas. 784 atm is well past water/airs critical P/T so at that point, you would simply have a one phase mixture of water and air combined. Feel free to read more on the phenomenon en.wikipedia.org/wiki/Supercritical_fluid. And there are also some cool youtube videos showing the effect.

    Just so you know, high vacuum is classified as pressures from 10^-7 torr on, or a millionth of atmospheric pressure. You achieved middle vacuum, barely, impressive with only a mechanical pump. You would need a diffusion pump to get lower.

    • @1pinosos1
      @1pinosos1 Před 7 lety +2

      Anyone know what kind of force would be acting on that (perspex?) door? It looked quite thin and had a large surface area so when he was talking about a 'high vacuum' it seamed a little concerning.
      Then again it didn't appear to flex in and become concave or anything so it must have been all good. Is that some kind of crazy strong door or was the force a lot less than i'm imagining?

    • @TheToric

      +J Paino
      That door seems to be about 1 foot in diameter. That's about 113 in^2 of surface area. And 1 atm of pressure equals to about 14.7 PSI.
      So, multiply both and we have about 1662 pounds of force.
      But it's not a complete vacuum so it's gonna be less than that.
