Entropy, Irreversible Transformations

This lecture covers the distinction between reversible and irreversible transformations, with examples such as irreversible expansions and mixing of ideal gases. It also delves into calculating entropy generation and internal entropy for different systems, including the demonstration of the lower efficiency of real cycles compared to Carnot cycles. The discussion extends to the concept of entropy in relation to heat exchanges and the representation of thermodynamic processes on T-S and p-V diagrams.
