Question

A heat engine in each cycle absorbs energy of magnitude  as heat from a high temperature reservoir, does work of magnitude , and then absorbs energy of magnitude  as heat from a low temperature reservoir.If  this engine violates:
A)the zeroth law of thermodynamics 
B)the first law of thermodynamics 
C)the second law of thermodynamics 
D)the third law of thermodynamics 
E)none of the above

Quizplus · Accepted Answer

The given equation violates the second law of thermodynamics, which states that the total entropy of a closed system always increases over time or remains constant in processes that are reversible. The given equation indicates that the engine is producing work without any decrease in entropy, which is not possible as it would violate the second law. Therefore, the correct answer is C.

A Heat Engine in Each Cycle Absorbs Energy of Magnitude
