Q2.

n kmol of a monatomic ideal gas is taken quasi-statically from state \(A\) to state \(C\) along the straight line shown; alternatively it is taken along the path \(ABC\). Express all answers in terms of \(P_A\) and \(V_A\). Take \(\gamma=\frac{5}{3}\). 

Match Column I with Column II: (A) heat \(\Delta H\) added along \(AC\); (B) change in internal energy along \(AC\); (C) work done along \(ABC\); (D) heat \(\Delta H\) added along \(ABC\).

(A)
\((A)\rightarrow(R), (B)\rightarrow(S), (C)\rightarrow(Q), (D)\rightarrow(P)\)
(B)
\((A)\rightarrow(S), (B)\rightarrow(Q), (C)\rightarrow(P), (D)\rightarrow(R)\)
(C)
\((A)\rightarrow(R), (B)\rightarrow(S), (C)\rightarrow(P), (D)\rightarrow(Q)\)
(D)
\((A)\rightarrow(Q), (B)\rightarrow(S), (C)\rightarrow(P), (D)\rightarrow(P)\)
