Thermodynamics: Entropy and Ideal Gases

This lecture covers the concepts of entropy, irreversibilities, and ideal gases in thermodynamics. The instructor explains the Clausius inequality, the three formulations of the second law, and the Carnot cycle. The lecture delves into the TDS equations, simplifications for incompressible substances, and the phase change of a substance. Additionally, it explores the entropy calculations for ideal gases, including the derivation of the TDS equation and the use of tables for entropy values.
