I ask thisquestion because I think there has never been liquid water on the surface of Mars.

Martian 'air pressure ' is about point 13 pound per square inch and Earths 'air pressure ' at sea level is 14 pounds per square inch.

I've read that the Martian 'air pressure' is equivalent to 100,000 feet up in Earths atmosphere.

There is no land on Earth that high so there is no possibility for a lake or stream but is it possible for liquid water like drops of water suspendend in the air to exists at that altitude.

OR back to the stated question :
At what air pressure will water vaporize at, close to or at freezing temperatures?



Where would a better place to post this be if this is not as good a place as I hope it will be.
I almost placed it in Chemestry , then I thought Earth Science , then Engineering, then Weather.
Then, since I was not sure , I placed it here in Other

Well, I have to do a research project on any scientist that works in any field of physics..and I got recommended from my teacher to do Stephen Hawkings..but when I try to research things on sites and such, all the information is hard to understand, considering I'm only in middle school. Would anyone be kind enough to help me and explain his theories (right or wrong) in a simpler way? o__o; Something maybe a middle school student can understand?
