3) A cup of rather dilute hot tea initially at 140 degrees F is served to a customer at Howard Johnson's. Unfortunately, before they get around to drinking it, it has spontaneously cooled off to 200 0 100 degrees F. Calculate the change in this process. The temperature of the entropy of the universe for restaurant (the surroundings) is 70 degrees F. (DHD 2/6/22) Suppose that the heat has problem 3, in order to save the inside temperature is been turned off in the HoJo's in money in the cold winter months, and 32 degrees F. The hot tea cools from HOWARD 140 degrees F to 32 degrees F, and then freezes, making it JOHNSON'S impossible to drink. What is the change in entropy of the universe in this case? (DHD 2/6/22) LCE CREAM 28 FLAVORS Restaurant Return to problem 3. Suppose that our customer complains about the cold tea and is given a second cup of hot tea. Feeling especially hungry (for tea?) they mix the hot tea and the cold tea together so that they will have twice as much tea (albeit luke warm). Assuming that the mixing occurs spontaneously and adiabatically, what is the final temperature of the tea, the change in entropy of the tea, and the change in entropy of the universe for the mixing process? (DHD 2/6/22) Whenever a process takes place spontaneously, there is "free energy" available for the taking if you are clever enough to figure out how to extract it. What is the maximum amount of work you could extract from the cooling process in problem 3. (DHD 2/6/22)
