Could Earth's moon support liquid water

based on water's properties and such, I think it could because it has an average temperature where water won't really be permanantly frozen or as a gas. Am I right or did I forget to consider something?

I'm sorry for asking all these questions. I don't go to actual school and do home/online schooling instead and I don't have a textbook so all I have is the web and I've been reading a lot of stuff on different websites but I can't really find an answer. So thanks :)

No, if you put liquid water on the Moon's surface it would vaporize in sunlight, and freeze in the dark. The reason for this is because the Moon lacks the atmospheric pressure to keep water in a liquid state.

Likely most of the larger moons have a bit of liquid water a few hundred miles below their surface (not practical for human habitation with present technology) where air pressure and temperature likely are close to Earth at sea level. Even a few feet below the surface a sealed in air envirornment is likely practical and the human activity would warm the habitat to a comfortable temperature which would melt the ice if there is any ice that close to the surface.

What you are i forgetting is atmosphereic air pressure. Yes, the Moon's water could be liquie in an artifical environment on the Moon becuase the artifician environment would have the required air pressure to deep the water liquid as long as it's temperature was high enough, because of the ideal gas law.

The moon has no atmosphere, the state of water depends on temperature AND pressure. Zero pressure makes it want to evaporate. However, there is reputable scientific belief that water ice exists at the polar regions in craters where the sun doesn't shine. Liquid water however, I highly doubt.

No. Water requires atmospheric pressure to remain in a liquid state. The
moon has no atmosphere.
