In a refrigerator, in one cycle, the external work done on the working

1.	In a refrigerator, in one cycle, the external work done on the working substance is 20% of the energy extracted from the cold reservoir. Find the coefficient of performance of the refrigerator.
Answer» Data: \|W\| = 0.2\|Q_C\| The coefficient of performance of the refrigerator, K = \(\|\frac{Q_C}W\|\) = \(\frac{\|Q_C\|}{0.2\|Q_C\|}\) = 5

Answer»

Data: |W| = 0.2|Q_C|

The coefficient of performance of the refrigerator,

K = \(|\frac{Q_C}W|\) = \(\frac{|Q_C|}{0.2|Q_C|}\)

= 5
