Learning Outcomes

On successful completion of this module students should be able to:

1. Explain the principles of the zeroth, first, second and third laws of thermodynamics.

2. Apply the laws of thermodynamics and kinetic theory of gases to analyse associated physical problems.

3. Present the principal thermodynamic steps in the operation of heat engines and calculate efficiencies.

4. Analyse thermodynamic processes in terms of the basic concepts of reversibility and entropy.

5. Describe the behaviour of real gases in contrast to ideal gases through the use of appropriate models and phase equilibrium diagrams.

Brief description

Following a brief recap of some of the basic ideas of thermodynamics, including the zeroth and first laws of thermodynamics, this module presents the the second and third laws of thermodynamics, introducing the concept of entropy. The kinetic theory of gases is presented, which provides the link between the macroscopic state variables and the microscopic quantities. Thermodynamic potentials and the Maxwell relations are introduced, with real gases and phase transitions also considered.

Aims

The module considers the laws of thermodynamics and associated thermodynamic properties. The module presents the kinetic theory of gases, and introduces the theories for real gases and phase transitions.
