Heat exchange primarily involves the transfer of energy in the form of kinetic energy. When heat is exchanged between objects, it is the result of the movement of particles. The faster the particles move (which correlates to higher temperatures), the more kinetic energy they possess. This movement can lead to a transfer of this kinetic energy from one object to another, constituting heat transfer.

In the context of heat exchange, other types of energy—such as electrical energy, sound energy, and nuclear energy—do not directly play a role in the transfer of heat as kinetic energy does. Electrical energy can produce heat through resistance in conductors, while sound energy involves vibrations in a medium which are not related to thermal energy transfer, and nuclear energy deals with reactions at the atomic level that release energy rather than transferring it in the form of heat. Therefore, kinetic energy is the relevant concept in understanding how heat is exchanged between objects.
