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.

Heated air rises because it is less dense than cold air. Cold air contains moisture so it falls as heated air rises. We can be grateful that it does or hot air balloons couldn't get off of the ground. You can find more information here: http://www.pa.msu.edu/sciencet/ask_st/042496.html
