Question

Suppose that a certain refrigerator is observed to remove 23 J of heat from its interior, while

drawing 12 J of energy from the electric grid and exhausting 35 J of heat to the kitchen in which

it sits. If the food inside the refrigerator is maintained at 2.85C and the room temperature of

the kitchen stays at 62.85C, then at what fraction of this refrigerator's theoretical maximum

possible coefficient of performance is its current operating coefficient of performance?
