← ScienceWhich characteristic increases when a Carnot engine cycle operates irreversibly?
A)Total entropy increases continuously.✓
B)Isothermal expansion happens effectively.
C)Cooling efficiency significantly improves.
D)Heat irreversibly becomes more ordered.
💡 Explanation
Irreversible processes generate entropy because heat transfer happens through non-equilibrium states, involving viscous behaviours; therefore, total entropy continuously accumulates, rather than having constant value like in pure reversible Carnot cycles under similar controlled conditions.
