The temperature inside and outside a refrigerator are 273 K and 300 K respectively. Assuming that the refrigerator cycle is reversible. For every joule of work done heat delivered to the surrounding will be nearly :-

A

9J

B

10J

C

13J

D

11J

Text Solution

Verified by Experts

The correct Answer is:
B
`beta=(Q_(2))/W=(T_(1))/(T_(H)-T_(1))`
`Q_(2)=W (T_(1))/(T_(H)-T_(1))`
`Q_(1)=(1 xx 273)/(303-273)`
`Q_(2)="9 Joule"`
`Q_(1)=Q_(2)+W rArr 9+1`
`Q_(1)="10 Joule"`
