Quizplus · Accepted Answer

The second law of thermodynamics states that in any energy conversion, some energy will be lost as unusable heat. Therefore, option B, which states that heat is usually given off from energy conversions, applies to the second law of thermodynamics. Options A, C, and D do not accurately describe the second law.
