Modes of Transferring Heat Thermodynamics
Heat is always transferred when a temperature difference exists between two bodies. There are three basic modes of heat transfer:
Conduction involves the transfer of heat by the interactions of atoms or molecules of a material through which the heat is being transferred.
Convection involves the transfer of heat by the mixing and motion of macroscopic portions of a fluid.
Radiation, or radiant heat transfer, involves the transfer of heat by electromagnetic radiation that arises due to the temperature of a body.
The three modes of heat transfer will be discussed in greater detail in the subsequent chapters of this module.
