"On the top of Mount Everest, where the air is very thin, the pressure of the air is so low that water will boil at about 65C - which made it very very hard for Sir Edmund Hilary to make himself a cup of tea in the afternoon!

In outer space, with no air at all, it would be impossible to keep the water together long enough to apply any heat. Any liquid water would begin to boil immediately you unscrewed the top of the bottle, or opened the tap, not because of the temperature, but because of the lack of pressure to hold the bubbles in."

In a vacuum, water does not boil but simply goes directly to a gaseous state. Ice will also change from a solid to a gas (sublimation) without melting if exposed to a low enough air pressure. NASA claims this is what happened to the ice found on Mars by the Lander's soil scoop, when it simply disappeared after being uncovered.
