← ScienceWhich effect reduces work output when a Carnot engine cycles too quickly?
A)Higher exhaust thermal energy
B)Reduced heat absorption efficiency
C)Irreversible heat transfer losses✓
D)Increased heat input temperature
💡 Explanation
When a Carnot engine cycles too rapidly, irreversible heat transfer appears because the working fluid cannot maintain quasi-static equilibrium, therefore entropy increases, which reduces theoretical efficiency; rather than A/B/D where values reflect ideal operation.
