everybody knows that hot air rises. but on thinking about heat as the knetic energy of molecules, heat transfer just becomes another word for collisions between molecules (looking at a gas) right?
so surely hot air, in it's attempt to rise from the bottom to the top of a container, would collide with colder air and hence heat these molecules and cause them to rise instead.
so basically what I'm wondering is does hot air rise, or is it just the heat that rises?
