A system can be taken from the initial state `p_(1),V_(1)` to the final state `p_(2,V_(2)` by two different methods, let `DeltaQ and DeltaW` represent the heat given to the system and the work done by the system. Which of the following must be the same in both the method?

`DeltaQ`

`DeltaW`

`DeltaQ+DeltaW`

`DeltaQ-DeltaW`

Text Solution

Verified by Experts

The correct Answer is:

Since initial and final states are same for two processes
`DeltaU_1=DeltaU_2=DeltaQ-DeltaW`
