← ScienceWhich thermodynamic limit results when a Carnot engine operates irreversibly?
A)Efficiency always decreases✓
B)Entropy remains constant
C)Heat input reduces
D)Work output maximizes
💡 Explanation
A Carnot engine undergoing irreversible processes generates entropy because it deviates its ideal operation; therefore, efficiency drops, reducing the reversible heat-work conversion, rather than increased output under ideal equilibrium conditions.
