Learning outcomes of the course unit
The aim of the course is to achieve an understanding of Classical Thermodynamics and to be able to use it in accounting for the bulk behaviour of simple physical systems.
Good working knowledge of calculus: functions of two or more variables, differential equations
Good working knowledge of classical mechanics
