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? |

Answer» 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` |
