Q Question 1 1 / 1 pts “Two objects in thermal equilibrium with a third object are in thermal equilibrium with each other.” Which Law of Thermodynamics is this? Correct! Question 2 1 / 1 pts “The entropy of an isolated system never decreases.” Which Law of Thermodynamics is this? Question 3 1 / 1 pts Which of the following quantities is not conserved? Question 4 1 / 1 pts You fill two identical mugs with coffee, but the coffee in one mug is at a higher temperature than that in the other mug. You place the two mugs simultaneously in a microwave oven and turn it on briefly. As a result, you add 1 joule of thermal energy to each mug. Which mug experiences the larger increase in entropy (if any)?Question 5 0.8 / 1 pts Suppose you claim to a friend that you have built a machine that follows the first law of thermodynamics – it converts heat energy directly into the same amount of work. Please comment as to whether you believe your friend or not.
