Which of the following scenarios accurately represents the second law of thermodynamics?

Question

Quizplus · Accepted Answer

The second law of thermodynamics states that entropy always increases in a closed system. In scenario A, the body converts glucose into ATP, and some of the energy is given off as heat. This heat increases the entropy of the system. In scenario B, the temperature of the car's engine increases as you drive to work. This is because the engine is a closed system, and the heat generated by the engine cannot escape. The increase in temperature increases the entropy of the system. In scenario C, when we are cold, our body shivers as a response to the decrease in body temperature. This shivering increases the entropy of the system.
