Medical Definition of Heat

1. Energy transferred between two objects because of a temperature difference, the thermal motion of atoms and molecules. For chemical systems the sign for heat flow into the system is positive, because this process increases the internal energy of the system. Heat flowing out of the system is defined to be negative, since this process decreases the internal energy of the system. (09 Jan 1998)
