Question

Match the items in Column I with Column II:

Column I	Column II
(P) Entropy of fusion at the melting point	(1) $\frac{Δ H _{f u s}}{T _{m}}$
(Q) Entropy of a perfect crystal at 0 K	(2) is zero
(R) $Δ G^{\circ}$ of a process with $K > 1$	(3) is negative
(S) Temperature of an ideal gas in reversible adiabatic compression	(4) rises

Choose the option with the correct matching:

(P) At the melting point solid and liquid are in equilibrium: $Δ S_{f u s} = Δ H_{f u s} / T_{m}$ (1).

(Q) Third law: $S = 0$ for a perfect crystal at 0 K (2).

(R) $Δ G^{\circ} = - RT ln K$ with $K > 1$ is negative (3).

(S) Work is done on the gas with no heat exchange, so its internal energy and temperature rise (4).

Correct matching: P→1; Q→2; R→3; S→4. Answer: (B).
