What happens to water in a total vacuum?

Question

Just wondering what happens to water in a total vacuum, like in space, but without the coldness.

Answer 1

It will boil until what's left freezes into snow crystals.  

Answer 2

It boils (flashes to vapor).  The lower the pressure, the lower the boiling point.  In a perfect vacuum, it flashes instantly at any point above freezing.

Answer 3

Bubbles will rise quickly to the surface until all the dissolved gasses have been released.

Answer 4

It is extremely cold in outer space but not a perfect vacuum.

Some extraneous gases are present.

Water in a total vacuum will boil and its vaporisation will decrease the temperature to freezing at the same time at a temperature close to absolute zero Kelvin. (-273°C).

Answer 5

Of course it's not a vacuum if water is present, but some of us are smart enough to understand what you mean.  Introduce some water into a sealed, evacuated chamber.  Some of the water will evaporate and some will stay liquid.  The concept is vapor pressure.  In space, it will evaporate as fast as the vapor can diffuse.  This evaporation draws heat from the remaining water (latent heat of vaporization), and will probably freeze it.

Answer 6

Reworded it, this could read "What happens to a sip of water when consumed by Paris Hilton".

Answer 7

Nothing. If the water's there it's not a vacuum.

Sorry, I felt like being sarcastic. Of course if this was actually a riddle, I think I solved it. :)

If you put water into what was a vacuum, however, it would be water vapor.
