I know that the boiling point of water is lower when the atmospheric pressure is less (such as at the top of a mountain), but why is that?
Once a water molecule has the energy to escape from the binding forces that keep it with the other water moelcules in the liquid, I don't understand why the movement of the surrounding air molecules (i.e pressure) alters the chances of escape of that molecule into the surrounding air?
