A refrigerator uses an ideal Carnot cycle to cool its interior. The outside air has a temperature of 302 K and the refrigerator is kept at a temperature of 276 K.
1) What is the coefficient of performance of this refrigerator?
2) If the refrigerator does 2300 J of work on the working substance, how much energy is transferred out of the refrigerator's interior?
J
3) In the scenario described in the previous question, how much energy is transferred into the outside air?
J
