1.	What is coefficient of performance of a refrigerator?
Answer» It is defined as the ratio of the amount of heat removed in a cycle from the refrigerator to the work done by some external agency to help the removal of this heat, i.e., β = \(\frac{Q_2}{W}\) = \(\frac{Q_2}{Q_1-Q_2}\) Also β = \(\frac{T_2}{T_1-T_2}\) For higher efficiency of refrigerator, β should be higher.

It is defined as the ratio of the amount of heat removed in a cycle from the refrigerator to the work done by some external agency to help the removal of this heat, i.e.,

β = \(\frac{Q_2}{W}\) = \(\frac{Q_2}{Q_1-Q_2}\)

Also β = \(\frac{T_2}{T_1-T_2}\)

For higher efficiency of refrigerator, β should be higher.
