s the cool part. in order for all these air-balls to not just fall down on the ground, they must have more collisions in the upward direction than the downward direction. this means that as you go lower in the atmosphere, the density of air increases, resulting in greater pressure. but...

Note that if we have different kinds of molecules with different masses, they go down with different exponentials. The ones which were heavier would decrease with altitude faster than the light ones. Therefore we would expect that because oxygen is heavier than nitrogen, as we go higher and hi...
