Is the transfer of thermal energy when particles of a fluid move from one place to another.

Most heating system use this kind og heat transfer to distribute thermal energy.

Is a device that reverses the normal flow of thermal energy. This device to work on a refrigerant

Convection curves are important in many natural cycles, for example.....

Is the transfer of energy by waves. All objects radiate energy.

What would happen to the objects radiation if the object temperature increases?
