1. A reversible refrigeration cycle operates between cold and hot reservoirs at temperatures TC and TH, respectively.

(a) If the coefficient of performance is 3.5 and TH 5 808F, determine TC, in 8F.

(b) If TC 5 2308C and TH 5 308C, determine the coefficient of performance.

2. An inventor has developed a refrigerator capable of maintaining its freezer compartment at 208F while operating in a kitchen at 708F, and claims the device has a coefficient of performance of (a) 10, (b) 9.6, (c) 4. Evaluate the claim in each of the three cases.
