When the state of a system changes from `A` to `B` adiabatically the work done on the system is `322` joule. If the state of the same system is changed from `A` to `B` by another process, and heat required is `50` calories of heat is required then find work done on the system in this process? `(J = 4.2 J//cal)`

Answer

`112` joule

Explanation

`dU_(1) = dU_(2), dQ_(1) - dW_(1) = dQ_(2) - dW_(2)`
`0 - 322 = 50 xx 4.2- dW_(2), dW_(2) =- 112J`.
