For an ideal gas, consider only P-V work...

For an ideal gas, consider only `P-V` work in going from an initial state `X` to the final state `Z`. The final state `Z` can be reached by either of the two paths shown in the figure. Which of the following choice(s) is (are) correct? [Take `DeltaS` as change in entropy and `w` as work done]

A

`DeltaS_(X to Z) = DeltaS_(X to Y) + DeltaS_(Y to Z)`

B

`W_(X to Y) = W_(X to Y) + W_(Y to Z)`

C

`W_(X to Y to Z) = W_(X to Y)`

D

`DeltaS_(X to Y to Z) = DeltaS_(X to Y)`
