Question: A refrigerator keeping 5oC inside is located in a 30oC room. It must have a high temperature T above room temperature and a low temperature

A refrigerator keeping 5oC inside is located in a 30oC room. It must have a high temperature ΔT above room temperature and a low temperature ΔT below the refrigerated space in the cycle to actually transfer the heat. For a ΔT of 0, 5 and 10oC respectively calculate the COP assuming a Carnot cycle.
