 The study of energy and energy movement is called thermodynamics.  Two laws govern the movement of heat in nature between objects.  These rules are termed the two laws of thermodynamics or heat movement.

The Law of Conservation of Energy Energy cannot be created or destroyed, it can only change form. Energy can have many forms, such as heat, light, and sound. This law states that energy can change form but is never really lost in a closed system.

Heat energy always travels spontaneously from a warmer body to a cooler body We have taken this law up in class already, but did not state it in this way The law is quite self-explanatory. Heat energy always moves out of a warmer body to a cooler one.
