Third Law and Statistical Thermodynamics

Third law and statistical thermodynamics at PGT depth: the Nernst heat theorem, absolute entropy scale, residual entropy exceptions, unattainability of absolute zero; Boltzmann statistics, microstates and ensembles, partition functions and their factorisation, derivation of thermodynamic functions from q, Maxwell–Boltzmann distribution of molecular speeds, and the bridge between statistical mechanics and classical thermodynamics.
