Which of the following statements is correct?
A)All the irreversible engines have same efficiency
B)All the reversible engines have same efficiency
C)Both Rankine and Caront cycles have same efficiency between same temperature limits
D)All reversible engines working between same temperature limits have same-efficiency

Question

Quizplus · Accepted Answer

The second law of thermodynamics implies that all reversible engines operating between the same two temperature limits have the same efficiency. This is a fundamental principle in thermodynamics, highlighting the maximum efficiency that can be achieved under ideal conditions. Options A, B, and C are incorrect because they either generalize incorrectly across all engines or misstate the conditions under which efficiencies would be equal.
