At what temperature would water boil on the moon?

Answer 1

It wouldn't.

Somewhere above -200 degrees C. (-400 F) it sublimates (goes from solid to vapor). That's how cold it gets in areas of the moon where they found ice, and at that low pressure it goes from solid straight to gas.

Answer 2

Boiling is a process when the vapour pressure of a liquid becomes equal or greater than the pressure above this liquid. If we use a pressure cooker, then the water will boil at a different temperature than if we try to boil it in an open pan, his is due to the fact that a pressure cooker gives some extra pressure hence boiling it at a lower temperature than its normal boiling point.
Well, to get a correct measure of boiling point, you have to be knowing whats atmospheric pressure there, although Moon's having a very thin or neglegeble atmosphere but atleast there is a atmosphere, hence water just cant boil at any temp on the Moon, but it is sure that water will boil at a temp very less than at which it boils on earth.

Answer 3

Although the Moon has a very thin atmosphere due to outgassing, most resources show that the surface pressure is simply 0. I found a boiling point of water calculator (third reference) that says the boiling point of water in a vacuum is 156.59 °F, which is much lower than the 212 °F boiling point of water at Earth's atmospheric pressure.

Answer 4

Water will not boil on moon. It will just evaporate if left in open as there is no atmospheric pressure and there is no water moisture in atmosphere.
