Question

an ideal refrigerator keeps it's content at 0 degree C while the room temperature is 27 degree C. calculate it's coefficient of perfomance​

Answer 1

The coefficient of performance is 10.11

Explanation:

The coefficient of performance is defined as the ratio of the heat extracted within a refrigerator to the work that is done of the refrigerator.

The temperature inside the fridge, T1 = 0°C, i.e., 273 K

The temperature outside the fridge, T2 = 27°C, i.e., 300 K

The coefficient of performance, CoP = T1 / (T2-T1)

                                                               = 273 / (300-273)

                                                               = 273 / 27

                                                               = 10.11

The coefficient of performance of the refrigerator is 10.11
