It's written multiple times in my textbook that
Some molecules at the surface of the liquid have kinetic energy more than those in the bottom, so they can escape from the surface.
But what causes them to have more kinetic energy or more speed (as far as I understand more k.e means a higher speed)
My usual guessing to why molecules at the surface only evaporate while the bottom don't is that maybe it has sth to do with the fact that the molecules at the surface only have to overcome the atmospheric pressure and the water molecules bonds under or next to them
But molecules at the bottom have to overcome bonds under, next and above them plus atmospheric and water pressure.
But I can't relate or make this guessing explain why molecules at the surface have more k.e than the bottom ones.
