Re: water in a vacuum

Water won't act any differently chemically in space than it does on earth; however, it will be a little strange that it won't stay in a container (due to the vastly decreased gravitational force of the Earth on the water molecules).

If you place liquid water in a vaccuum, it will immediately boil and change state into a gas. All hydrogen bonds will be broken.

Also, if you freeze water in a sealed tube, chances are it will deform the tube since ice takes up a greater volume than liquid water. This, of course, depends on how much air you seal in the water with...

That makes no sense. What does it mean to "decrease the amount of electricity"? Electricity deals only with charges; water is electrically neutral overall, but does have the slight positive and negative regions within a single water molecule that make hydrogen bonding possible. I don't see how this works...

Was -40 (degrees Fahrenheit?) the temperature of the air or the water? Seawater has a lower freezing point than 32 degrees Fahrenheit due to its high salt content (freezing point depression). Also, a layer of ice on any body of water insulates the water below, allowing it to remain liquid (hence allowing life to go on in a frozen pond). Tweet
