Why Does Heat Rise?

Answer

Heat in itself does not rise as there is no matter in heat although it causes air to rise. Heated air is generally less dense than cold air causing it to rise above the cold air which contains moisture. Heat may be transferred from one object to another through the processes of radiation, conduction and convection.
