The coefficient of performance of refrigerator, whose efficiencty is 2

1.	The coefficient of performance of refrigerator, whose efficiencty is 25% isA. 1B. 3C. 5D. 7
Answer» Correct Answer - B The efficiency of refrigerator is `eta`=25% =0.25 `therefore` coeffiecient of performance `beta=(1-eta)/(eta)=(1-0.25)/(0.25)=(0.75)/(0.75)=3`
