___1. Based on the zeroth law of thermodynamics, explain why a can of soft drink remains at a constant cool temperature inside a refrigerator. A. The amount of heat flowing into the can is not equal to the heat flowing out. B. It is in thermal equilibrium with its surroundings. C. It is cooler inside the refrigerator. D. The temperature in variable inside a refrigerator. ___ 2. Which of the following systems does not show increase in entropy? A. An egg is broken and scrambled. B. A reshuffled deck of cards. C. Juice freezing into ice pops. D. Fixing your messy clothes cabinet. ___ 3. Would it be possible to cool a room by opening the door of the refrigerator? A. No, the heat exhausted into the room from the condenser of the refrigerator is more than that removed from the room. B. No, the room is too large to cool. C. Yes, the condenser of the refrigerator can cool down a room. D. Yes, the heat exhausted into the room from the condenser of the refrigerator is less than that removed from the room. ___ 4. Why does boiling water using electricity result in a larger increase in the entropy of the universe? A. It is not very efficient since much energy is lost by heat to the surrounding air. B. It is very efficient since much energy is lost by heat to the surrounding air. C. Adding water decreased the change in entropy of the air produces a larger increase in entropy of the universe. D. Adding water added to the change in entropy of the air produces a larger increase in entropy of the universe.
