Heat is defined as energy transferred by virtue of a temperature difference. It flows from
regions of higher temperature to regions of lower temperature. It is customary to refer to different
types of heat transfer mechanisms as modes. The basic modes of heat transfer are conduction,
radiation, and convection.
Conduction is the transfer of heat from one part of a body at a higher temperature to another
part of the same body at a lower temperature, or from one body at a higher temperature to
another body in physical contact with it at a lower temperature. The conduction process takes
place at the molecular level and involves the transfer of energy from the more energetic
molecules to those with a lower energy level. This can be easily visualized within gases, where
we note that the average kinetic energy of molecules in the higher-temperature regions is
greater than that of those in the lower-temperature regions. The more energetic molecules,
being in constant and random motion, periodically collide with molecules of a lower energy
level and exchange energy and momentum. In this manner there is a continuous transport
of energy from the high-temperature regions to those of lower temperature. In liquids the
molecules are more closely spaced than in gases, but the molecular energy exchange process
is qualitatively similar to that in gases. In solids that are nonconductors of electricity (dielectrics),
heat is conducted by lattice waves caused by atomic motion. In solids that are good conductors of electricity, this lattice vibration mechanism is only a small contribution to the
energy transfer process, the principal contribution being that due to the motion of free electrons,
which move in a similar way to molecules in a gas.
