← ScienceWhich outcome occurs when inefficiencies reduce a Carnot engine's cycle?
A)Entropy increases in each cycle✓
B)Net work output approaches maximum
C)Isothermal expansion approaches irreversibility
D)Adiabatic compression becomes more reversible
💡 Explanation
Entropy increases because inefficiencies introduce irreversibilities in the cycle via increased friction and heat loss; therefore, entropy generation grows above zero each cycle, rather than being ideally constant at zero for reversible idealized cycles.
