except.
The relative masses are:

water (HOH) 18

nitrogen (NN) 28

oxygen (OO) 32

So if the molecules were equally spaced apart, water would be least dense. This is what actually occurs in the gas phase, water vapor is less dense than air. Water is mostly in the liquid phase, with molecules much closer to each other, at room temperature and atmospheric pressure due to intermolecular forces.

So besides gas form u have liquid form n then they r just dumping liquid down.
