Question

question 13 matching consider the laws of thermodynamics. prompts answers ① what is the capacity to do work? work ② which law of thermodynamics states that the amount of unusable energy decreases every time energy changes from one form to another? 2nd law

Explanation:

1. By definition, energy is the capacity to do work.
2. The second - law of thermodynamics states that the entropy (amount of unusable energy) of an isolated system always increases over time, not decreases. The statement in the question is incorrect. But if we assume a mis - statement and go by the idea of usable energy increase during energy conversion, the second - law is related to energy quality changes.

Answer:

1. Energy
2. None of the above (since the statement about the second - law in the question is wrong)
