[Question] Why is air that contains a lot of water vapor less dense than drier air? [Answer]
|
Water vapor molecules have less mass than nitrogen or oxygen molecules. The lighter water vapor molecules replace an equal number of heavier oxygen and nitrogen molecules, making the volume of air less dense.
