The hot water molecules become less dense, and they rise above the denser cooler molecules. Boiling water is an example of forced convection.

Why does convection occur in heated fluids?

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Liquids and gases expand when they are heated. This is because the particles in liquids and gases move faster when they are heated than they do when they are cold.
