Classical approximation, Maxwell Velocity distribution, the equipartition theorem, the specific heat of solids. General thermodynamic interaction between systems. Dependence of number of states on the external parameters. General thermodynamic relation at equilibrium. Thermodynamic potentials. Legendre Transformations. Second and third law of thermodynamics. Equilibrium conditions of an isolated systems and a system in contact with reservoir. Equilibrium between phases. Gibbs phase rule. Elementary kinetic theory of transport process. Viscosity, conductivity, self-diffusion, electrical conductivity. Boltzmann transport equation.
