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 $Δ S$ as change in entropy and w as work done].

TestHub · Accepted Answer

Δ S X → Z ​ = Δ S X → Y ​ + Δ S Y → Z ​ [Entropy is a state function, hence additive] w X → Y → Z ​ = w X → Y ​ [Work done in Y → Z is zero because it is an isochoric process].
