Question

Quizplus · Accepted Answer

The second law of thermodynamics states that when energy is converted from one form to another, some of that energy becomes unusable. This is known as the law of entropy, which states that the total amount of entropy (or disorder) in a closed system always increases over time. Therefore, choice A is the most accurate statement of the second law of thermodynamics.
