Science

Which consequence occurs when operating a real heat engine undergoing non-ideal, irreversible, Carnot-like, cycles?

A)Entropy increase exceeds cycle efficiency
B)Energy transforms become fully reversible
C)Internal energy remains perfectly unchanging
D)System isothermal stages require no energy

💡 Explanation

Real engines generate more entropy than a Carnot cycle because of non-ideal processes causing increased disorder, therefore, cycle efficiency declines rather than remaining optimal, and isothermal stages still necessitate external energy introduction to proceed.
