Well, I've experienced a wierd event in the dead of winter last year; At 12F there was liquid water in my car's plastic (PET) water bottle... I had drank about 1/3 of the bottle the evening earlier,...
Elevation has minimal affects on the freezing point of water as it doesn't deal with gas molecules as boiling does. Elevation affects the boiling point of water because the air pressure changes with...
The freezing point decreases slightly with increased pressure. See the phase graph at the related link. I do remember seeing a science fair project, where the student attached a weight to a fishing...
The only factor that determines the boiling point of water at any altitude is the barometric pressure (the altitude itself doesn't actually matter, it's just that at higher elevation, the barometric...
