SUMMARY
This discussion focuses on the concept of irreversible processes in thermodynamics, specifically addressing examples and their irreversibility on a microscopic scale. Two examples provided include an engine operation, which experiences Joule heating and friction, and any real process where the system and surroundings are not in equilibrium. The discussion emphasizes that irreversible processes cannot return to their initial states without external work, highlighting the fundamental principles of entropy and thermodynamic equilibrium.
