Question

A. This engine satisifes the 2nd law of thermodynamics because its thermal efficency is lower than its ideal efficiency

B. This enginer satisfies the 2nd law of thermodynamics since its thermal efficency is higher than the ideal efficiency

C. This engine does not satisfy the 2nd law of thermodynanics since its thermal efficiency is lower than the ideal efficiency.

D. This engine does not satisfy the 2nd law of thermodynamics since its thermal efficiency is higher than the ideal efficiency.

E. None of the above

Explanation / Answer

A. This engine satisifes the 2nd law of thermodynamics because its thermal efficency is lower than its ideal efficiency

According to Second law of thermodynamics, no heat heat engine can have more efficiency than ideal heat engine.
