The co-efficient of performance (COP) of a refrigerating system, which is its index of performance, is defined as the ratio of useful refrigeration to the net work. The units of __________ and COP are the same.
A. Kinematic viscosity
B. Work
C. Temperature
D. None of these
Answer: Option D
Solution(By Examveda Team)
COP of refrigerating system $$ = \frac{{{\text{heat taken from the low temperature reserviour}}}}{{{\text{work supplied}}}}$$So, we can say there are no units for COP because the heat taken and work both are energy in transits and therefore have same units.
