The temperature inside a refrigerator is t2 ​ C and the room temperature is t1 ​ C. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be

A

`(t_(1))/(t_(1)-t_(2))`

B

`(t_(1)+273)/(t_(1)-t_(2))`

C

`(t_(2)-273)/(t_(1)-t_(2))`

D

`(t_(1)+t_(2))/(t_(1)+273)`

Text Solution

Verified by Experts

The correct Answer is:
B

`(Q_(1))/(W)=(Q_(1))/(Q_(1)-Q_(2))=(t_(1)+273)/(t_(1)-t_(2))`
