A certain mass of is taken from an initial thermodynamics state `A` to another state `B` by process I and II. In process I for the gas does `5 J` of work and absorbs `4 J` of heat energy. In process II, the gas absorbs `5 J` of heat. The work done by the gas in process II is

Text Solution

Verified by Experts

The correct Answer is:
6
For process I : `dQ = dU + dW`
`implies 4 = dU + 5 implies dU = -1`
For process II : `5 = dU + dW`
`implies = - 1 + dW implies dW + dW`
