Which energy dissipation occurs in irreversible Carnot engine operating between two finite reservoirs?

💡 Explanation

In an irreversible Carnot engine, frictional heating arises due to imperfect mechanical components, thereby increasing total system entropy because the heat conversion process is not perfectly reversible. Therefore, increased entropy occurs due to frictional heating, rather than quantum tunneling, magnetic hysteresis, or catalytic conversion which reflect different physical mechanisms.
