A bottle of water at 0'C is opened on the surface of moon. What happens and why?

daveb said:It's a somewhat more complicated picture than that. Boiling point rises and lowers with increasing and decreasing atmospheric pressure. Since there is no air pressure to speak of on the moon, the boiling point should be much lower than 100C. However, in order to change from the solid (remember it's at 0 degrees initially) it starts as a chunk of ice, and boils off at a rate that depends upon the radiation flux (which would impart sufficient energy to teh H2O molecules to allow them to escape). The higher the flux, the faster it boils off.

The water will quickly boil and evaporate due to the low atmospheric pressure on the moon's surface. This is because the boiling point of water is lower at lower pressures, and there is almost no atmospheric pressure on the moon.
The lack of atmosphere on the moon means there is no air pressure to keep the water molecules from escaping into the air as gas. Additionally, the low atmospheric pressure means that the water's boiling point is much lower than at sea level on Earth.
No, it is not possible for liquid water to exist on the moon's surface at 0°C. The lack of atmospheric pressure and extreme temperatures make it impossible for liquid water to exist in its natural state on the moon.
The lack of atmosphere on the moon greatly affects the behavior of water. Without atmospheric pressure, the water molecules have no force holding them together, causing them to quickly escape into the air as gas. The low atmospheric pressure also means that water will boil at much lower temperatures than on Earth.
No, water cannot be stored or transported on the moon's surface at 0°C. It would quickly boil and evaporate due to the lack of atmospheric pressure, making it impossible to maintain a liquid state. Special equipment and conditions would be needed to store and transport water on the moon's surface.
