Here I demonstrate how one can approximate the thermal/vibrational contribution to the entropy of solids based upon the Einstein approximation. The experimental heat capacity is used to determine the Einstein frequency. (F22_Ex7.2)

Here I demonstrate how one can approximate the electronic contribution to the entropy of simple metals approximating them using the free electron gas model. (F22_Ex7.3)

Here I demonstrate and discuss the solution to Problem 4.1 from David Gaskell's textbook "Introduction of the Thermodynamics of Materials" Third Edition. (F22_Ex7.1)

This lecture expands upon our understanding of statistical physics. It is demonstrated how the Ergodic theorem allows for our understanding of measurement as a sampling from an ensemble of systems. Analytical forms of configurational, thermal, and electronic entropy are given, including simplifications coming from the Einstein and Debye approximations. The electronic entropy is expressed using the free electron model for the density of states. (F22_L10)

In this lecture I give an introduction to statistical physics. The ideas of microstates and macrostates are expanded upon. The partition function is derived based on the counting of microstates constrained by the conservation of energy and particle number. The Boltzmann equation, relating the number of microstates and entropy, is derived. (F22_L09)

In this lecture I define the passage of heat and work into a system as it related to the total energy. We see that variables can be collected in a convenient fashion that we define as the Enthalpy. Within the context of gasses we define the constant pressure and constant volume heat capacities.
