For a refrigerator , heat absorbed from ...

For a refrigerator , heat absorbed from source is 800 J and heat supplied to sink is 500 J then find coefficient of performance is :-

A

`(5)/(8)`

B

`(8)/(5)`

C

`(5)/(3)`

D

`(3)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
Coefficient of performance `=(Q)/(Q_(1)-Q_(2))=(500)/(800-500)=(5)/(3)`
