E)none of the above

Question

Quizplus · Accepted Answer

The described heat engine violates the second law of thermodynamics, which states that it is impossible for a heat engine to convert all input heat into work with no other changes, as some heat must always be expelled to the surroundings. This is known as the Kelvin-Plank statement of the second law.
