Explain Question: Match list-I with list-II.

Concept: Thermodynamic parameter.

Solution:

(P) $Δ T > 0 \Rightarrow Δ H > 0, Δ U > 0$ , expansion $\Rightarrow W < 0$ and $q > 0$ (since $Δ U = q + W$ )

(Q) $Δ T = 0 \Rightarrow Δ H = Δ U = 0$ , expansion $\Rightarrow W < 0$ and $q > 0$

(R) $Δ T > 0 \Rightarrow Δ H > 0, Δ U > 0$ , expansion $\Rightarrow W < 0$ and $q > 0$

(S) $P = co n s t an t \Rightarrow q = Δ H$ , since compression $\Rightarrow Δ T < 0$ and $W > 0$ .

Final Answer: Option (B)
