8 Thermal energy transport

When different parts of a body are at different temperatures, heat flows from the hotter parts to the cooler. There are three distinct methods by which this transference of heat takes place: (1) conduction, in which heat passes through the substance of the body itself; (2) convection, in which heat is transferred by relative motion of portions of the heated body; and (3) radiation, in which thermal energy is transferred directly between distant portions of the body by electromagnetic radiation. We will not discuss convection in this work, and radiation transfer will be discussed in Chapter 9.

In general, a temperature gradient will be accompanied by a pressure gradient as can be seen in an equation of state, such as that ...
