It would boil and vaporize at room temperature! And it has NOTHING to do with so-called "high energy radiation from the Sun!!!"
Liquid water can only exist because it requires an atmospheric pressure pushing the water molecules back together. Otherwise it only exists as a frozen or gaseous state.
If you happened to open a bottle of liquid water on surface of the moon, that implies it has some heat and air pressure beforehand in order to remain liquid.
In order for that heat to dissipate, the water would boil and vaporize. It would not freeze, because the only method of heat dissipation in a vacuum is radiation, which is slow compared to conduction or convection. Conduction and convection can only occur within an atmosphere or something else similar.
Hope this helps -- this answer is NOT ba
it will just fly out of the bottle, hopefully the bottle won't explode first
Actually, it would instantly boil, and then the molecules would be ripped apart due to the high energy radiation of the sun.
she beat me to it
