35. A Carnot refrigerator working between a hot reservoir at temperature T H and a cold reservoir at tem- perature T L has a coefficient of performance K that is given by K = T L / ( T H T L ). For the refrigerator of this problem, T H =96 F = 309 K and T L =70 F = 294 K, so K = (294 K)

Unformatted text preview: / (309 K 294 K) = 19 . 6. The coecient of performance is the energy Q L drawn from the cold reservoir as heat divided by the work done: K = | Q L | / | W | . Thus, | Q L | = K | W | = (19 . 6)(1 . 0 J) = 20 J....
