Humid or dry air "heavier"?
It would seem that the addition of water vapor in the air would increase the mass of the volume of air thus making it "heavier." However, the professor in class today said humid air is typically heavier because humid air has water vapor as opposed to the more massive nitrogen and oxygen molecules. Does the water vapor somehow displace/replace the nitrogen and oxygen molecules?
