Question

Quizplus · Accepted Answer

The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed in an isolated system. Choices B, C, and D accurately reflect principles related to this law. However, choice A describes a concept related to the second law of thermodynamics, which deals with the quality of energy and states that when energy is converted from one form to another, the amount of useful energy decreases due to entropy.
