Question

A carnot refrigerator uses an ideal carnot cycle to cool its interior. The outside air has a temperature of 304 K and the refrigerator is kept at a temperature of 279 K.

1) What is the coefficient of performance of this refrigerator?

2) If the refrigerator does 1500 J of work on the working substance, how much energy is transferred out of the refrigerator's interior?

3) In the scenario described above, how much energy is transferred into outside air?
