Please consider 1 kg of saturated water initially at 0 °C that was heated to become saturated water at 100 °C. a. Case 1: The water was heated by an extremely large object at 150 °C. Please determine the change in entropy of (i) the water, (ii) the large object, and (iii) the universe. b. Case 2: The water was heated by an extremely large object at 100 •C. Please determine the change in entropy of (i) the water, (ii) the large object, and (iii) the universe. c. Case 3: The water was heated in a two-step process. First, the water was heated to 50 C by an extremely large object at 50 °C and then the water was heated to 100 •C by an extremely large object at 100 •C. Please determine the change in entropy of (i) the water, (ii) the very large object at 50 °C, (iii) the very large object at 100 •C, and (iv) the universe. d. Based on the results of Cases 1-3, please suggest a process that will heat the water from 0 C to 100 °C with little or no entropy change in the universe. For the problem above, please express entropy or entropy change with units of J, K, kg, and/or sec.

2. Please consider 1 kg of saturated water initially at 0 C that was heated to become saturated water at 100 °C. a. Case 1: The water was heated by an extremely large object at 150 C. Please determine the change in entropy of (i) the water, (ii) the large object, and (iii) the universe. b. Case 2: The water was heated by an extremely large object at 100 °C. Please determine the change in entropy of (i) the water, (ii) the large object, and (iii) the universe. c. Case 3: The water was heated in a two-step process. First, the water was heated to 50 °C by an extremely large object at 50 °C and then the water was heated to 100 °C by an extremely large object at 100 "C. Please determine the change in entropy of (i) the water, (ii) the very large object at 50 C, (iii) the very large object at 100 •C, and (iv) the universe. d.
