Nitrogen, because the molecules are lighter and therefore they spread out quicker.To know the lighter objects we will check the molecular mass(Mr)by seeing the upper number in the periodictable


What happens when water vapor is lighter than nitrogen or oxygen?

Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.

Does nitrogen dioxide diffuse faster than neon?

No. Gaseous diffusion is a function of mass, with lighter molecules diffusing more rapidly. Neon (approximate atomic mass of 20) is considerably lighter than nitrogen dioxide (approximate molecular mass 46).
