Pre-requisites

PHYS1041, PHYS1150 and PHYS1160 or equivalent

This module is not approved as an Elective

Objectives

On completion of this module students should be able to:
- demonstrate their continued attainment of the learning outcomes of PHYS1041 (Thermal Physics);
- use Boltzmann, Fermi-Dirac or Bose-Einstein statistics as appropriate to deduce the thermodynamic properties of systems such as: a simple solid; a paramagnetic solid; a free-electron gas; and black body radiation;
- relate the transport properties of gases to a simple atomistic model using the mean free path concept;
- discuss the concept of entropy from both the thermodynamic and statistical points of view and calculate entropy changes in irreversible processes;
- define Enthalpy, the Helmholtz function and the Gibbs function and discuss their utility;
- state and discuss the four laws of thermodynamics and the various alternative formulations of each law;
- use these laws, and Maxwell relations or the TdS equations to solve thermodynamic problems; and
- describe the phase diagram for a simple material, derive the Clausius-Clapeyron equation and use it to solve problems relating to the change in a phase transition temperature with pressure.
