Quantum physics is at the core of physics and this unit provides a basis for understanding key quantum concepts, applications and associated phenomena. Thermal physics aims to understand how energy resides in matter as thermal energy, how energy moves irreversibly as heat between bodies at different temperatures, and how heat flow arises from entropy and the second law of thermodynamics; entropy is defined carefully in terms of the multiplicity of microstates of a system. Thermal physics explores how work can be interconverted with thermal energy and how entropy limits the efficiency of engines, heat pumps and refrigerators.
