After taking this module students should be able to:
- describe such ideas as phase changes.
- describe low temperature phenomena from a macroscopic and microscopic point of view.
- explain the basic concepts of statistical mechanics and their application to investigate the properties of matter.
a) build on the introductory thermodynamics course, introducing such ideas as phase changes.
b) introduce phenomena that occur at low temperatures, and to explain these from both a macroscopic and a microscopic point of view.
c) introduce the concepts of statistical mechanics, and use these to investigate the properties of matter.
Thermodynamic potential - internal energy U, enthalpy H, Helmholtz function F and Gibbs function G and their physical significance.
The Maxwell relations.
Derivation of general thermodynamic relations for pure substances.
Phase transitions - first order and higher order transitions.
The attainment of absolute zero temperature.
- Liquefaction of gases (Joule-Kelvin effect)
- Adiabatic paramagnetic and nuclear demagnetisation
- the Third Law of Thermodynamics - the unattainability of absolute zero Liquid helium and superfluidity Superconductivity. Conventional superconductors and the BCS theory. Survey high Tc superconductors.
- Assembly of distinguishable particles: Boltzmann distribution, Partition function, link to thermodynamic quantities, examples
- Assembly of indistinguishable particles (gases): Fermi-Dirac and Bose-Einstein distributions, Maxwell-Boltzmann distribution, examples
