General Physics III (Behaviour of Matter)
2
Course Description
On completion, the students should be able to:
1. explain the concepts of heat and temperature and relate the temperature scales;
2. define, derive and apply the fundamental thermodynamic relations to thermal systems;
3. describe and explain the first and second laws of thermodynamics, and the concept of
entropy;
4. state the assumptions of the kinetic theory and apply techniques of describing macroscopic
behaviour;
5. deduce the formalism of thermodynamics and apply it to simple systems in thermal
equilibrium; and
6. describe and determine the effect of forces and deformation of materials and surfaces.
