The unit begins with a comparison of the ways of describing a physical system in terms of both macroscopic and microscopic viewpoints, and simple relations between them, such as temperature. The unit explores the zeroth, and first Laws of thermodynamics, including the concepts of heat capacity and enthalpy. Exploration of the second law of thermodynamics is used to describe the operation of heat engines and Carnot cycles. The concept of entropy is introduced, and some of its properties are examined using the third law of thermodynamics. It then examines thermodynamic potentials and phase changes in substances. The final part of the unit explores the kinetic theory of gases and statistical... -- Course Website
