  1. Thermal Physics II Part 2 A) Thermodynamic Potentials & Maxwell Relations B) Statistical Thermodynamics http://ppewww.ph.gla.ac.uk/~parkes/teaching/TP/TP.html Chris Parkes

  2. Statistical Thermodynamics • Microstates, Energy Levels • Boltzmann Factor • Partition Function • Calculating Average • Microscopic Definition of Internal Energy • Helmholtz Function • Quantum Harmonic Oscillator • - Planck Expression • - Equipartition – Classical & Quantum • Vibrations in Solid • - Einstein model, (Debye) • Blackbody Radiation • - Stefan’s Law • Indistinguishable Particles: Fermions & Bosons

  3. Specific Heat Capacity Dulong-Petit cv=3R • For Crystalline solid • Dulong-Petit equivalent to classical equipartition • Einstein, independent oscillating atoms • Debye, atomic vibrations as phonons in a box

  4. Blackbody Radiation
