Efficiency of a Carnot cycle is derived based on the
(A) first law of thermodynamics
(B) second law of thermodynamics
(C) third law of thermodynamics.
(D) Boyle’s law
The correct answer is:
(B) second law of thermodynamics
Explanation:
The efficiency of a Carnot cycle is derived using the second law of thermodynamics, which states that no engine operating between two heat reservoirs can be more efficient than a reversible engine (like the Carnot engine) operating between the same reservoirs.
