how does air pressure affect water boiling/ freezing points
In: 1
Easiest explained with boiling point.
When water boils, molecules of water are flying off the surface of the water body. When the air pressure is high, the air in contact with the water is pushing harder on the surface of the water and preventing it from flying away to a greater degree.
The opposite is also true, low pressure means water can fly away easier, thus the boiling point is reduced.
