In hot air the molecules move faster and exert more force when they collide. As a result there is more space in between the molecules on average.

Why does warm water stay on top of cold water?

Warm water tends to stay on top of cold water because it is less dense. When water is heated, the molecules move farther apart, making warm water less dense than cold water. This difference in density causes warm water to float on top of cold water.

Why does warm water sit on top of cold water?

Warm water is less dense than cold water, so it sits on top of the cold water. This is because warm water molecules are more spread out and have less mass per unit volume compared to cold water molecules, causing warm water to be less dense and float on top of the denser cold water.
