Subject Description

This subject explores concepts such as heat, temperature and internal energy via the classical phenomenological approach to thermal physics as well as the atomistic approach provided by kinetic theory. The theories discussed are central to an understanding of many processes in physics, chemistry and engineering. Students will develop the skills to apply these concepts to understanding a variety of phenomena in physical systems. The content will include basic concepts: thermodynamic variables. Zeroth law: heat; temperature and its measurement; temperature dependence of material properties. Equations of state: special processes; differential changes of state; work. First law: internal energy; enthalpy; heat capacities; latent heats. Second law: heat engines; efficiencies; entropy and its use; Free energies; Kinetic theory: Maxwell distribution; efflux; transport theory; conductivity; black body radiation.

Assessment

A 2-hour end-of-semester written examination plus tests and/or assignments, set during the semester, which may account for up to 20% of the final marks.
