It is due to the kinetic energy of the composition of matter, which include atoms and molecules. Similar to the kinetic energy of a bowling ball, where the kinetic energy is zero if the ball is stationary and positive if the ball is moving, heat is the measure of how much energy is transferred between objects of different temperatures. If there is no temperature difference, then the heat energy is zero. Since Heat is energy, the SI unit is the joule. {\bf References} [1] Halliday, D., Resnick, R., Walker, J.
