If heat Q is added reversibly to a system at temperature T and heat `Q'` is taken away from it reversibly at temperature `T'`, then which one of the following is correct

A

`Q/T - (Q')/(T)=0`

B

`Q/T - (Q')/(T) gt 0`

C

`Q/T - (Q')/(T) lt 0`

D

`Q/T - (Q')/(T)` change in internal energy of the system

Text Solution

Verified by Experts

The correct Answer is:
B
Since, `Q gt Q.`
`implies Q/T gt (Q.)/(T) implies Q/T - (Q.)/(T) gt 0`
