Thermal Physics: Thermodynamics and Statistical Mechanics

Thermal Physics: Thermodynamics and Statistical Mechanics 

Robert F. Sekerka

Preference :

Thermal physics deals with the quantitative physical analysis of macroscopic systems. Such systems consist of a very large number, N , of atoms, typically N ∼ 1023. According to classical mechanics, detailed knowledge of the microscopic state of motion (say, position ri and velocity vi) of each atom, i = 1, 2, ... , N , at some time t, even if attainable, would constitute an overwhelmingly huge database that would be practically useless. More useful quantities would be averages, such as the average kinetic energy of an atom in the system, which would be independent of time if the system were in equilibrium. We might also be interested in knowing such things as the volume V of the system or the pressure p that it exerts on the walls of a containing vessel. In other words, a useful description of a macroscopic system is necessarily statistical and consists of knowledge of a few macroscopic variables that describe the system to our satisfaction.
