1.	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_(xtoz)=DeltaS_(xtoy)+Delta_(ytoz)`B. `w_(xtoz)=w_(xtoy)+w_(ytoz)`C. `w_(xtoytoz)=w_(xtoy)`D. `DeltaS_(xtoytoz)=DeltaS(xtoy)`
Answer» Correct Answer - A::C Entropy is state function, while work is the path dependent function `DeltaS_(xtoz)=DeltaS_(xtoy)+DeltaS_(ytoz)` `w_(xtoytoz)=w_(xtoy)`.
