A system goes from P to Q by two different paths in the `P-V` diagram as shown in (figure). Heat given to the system in path 1 is `1000J`. The work done by the system along path 1 is more than path 2 by `100J`. What is the exchange by the system in path 2?

Text Solution

Verified by Experts

In (figure) `dQ_(1)= dU+dW_(1)`
and `Q_(2)=dU+dW_(2)`
`:. dQ_(1)-dQ_(2)= dW_(1)-dW_(2)`
`1000-dQ_(2)= 100`
`dQ_(2)= 1000-100= 900J`
