Part 1: Five thousand kilocalories (5000 kcal) of heat flows from a high temperature reservoir at 600 K to a low temperature reservoir at 300 K. What is the entropy change in the universe? Part 2: Now let us assume the same 5000 kcal of heat flows through a 20% efficient heat engine between the same reservoirs. a. Compute amount of heat converted into useful work. b. Compute the entropy change in the universe.
