The given P-V diagram indicate that
process ABCD is non-cyclic process
Total work done is negative in process ABCD
Both A and B
Only A
As we have learned
Non Cyclic Process -
The series of changes involved do not return the system back to its initial state.
- wherein
This is non-cyclic process as it is not returning to initial state
Work done is area under P-V curve here negative work done is more than positive work done
