The purpose of thermodynamics is to describe the properties of various macroscopic systems at, or near, equilibrium. This is done with the help of several state variables, such as the internal energy E, the volume V , the pressure P, the number of particles N, the temperature T, the entropy S, the chemical potential µ, and others. These state variables depend only on what the state of the system is, and not on how the system was brought to that state. The variables are not all independent, and thermodynamics provides general relations among them. Some of these relations are not specific to particular systems, but are valid for all macroscopic systems.
