7. The second law of thermodynamics leads us to conclude that (2 pts) A) the total energy of the universe is constant B) disorder in the universe is increasing with the passage of time C) it is theoretically possible to convert heat into work with 100% efficiency. Dj the average temperature of the universe is increasing with the passage of time. E) the entropy of the universe remains constant 8. What is the change in entropy when 15.0 g of water at 100°C are turned into steam at 100 C? (6 pts) A) 339 1/K 8)-90.81/ C)90.81/ D)-339 1/K E) o Jpw 9. A 35-N bucket of water is lifted vertically 3.0m and then returned to its original position. How much work did gravity do on the bucket during this process? (2 pts) A)1801 8) 901 C) 45) E) 9001 0. A glass window pane is 2.7 m high, 2.4 m wide, and 9.0mm thick. The temperature at the inner surface of the glass is 19C and at the outer surface 4C. How much heat is lost per second through the window? (5 pts) A) 9.1 10 w 8)9.1W C) 82 W D) 735 w E) 0.735 W
