Question

Match gases under specified conditions listed in Column-I with their properties/laws in Column-II. Indicate your answer by darkening the appropriate bubsbles of the 4 4 matrix given in the ORS.

Answer 1

(A) $Z=\frac{P{V}_m}{RT}$ at high pressure and low temperature.
Equation $(P+\frac{a{n}^2}{V^2}\left)\right(V-$ nb $)=nRT$ reduces to $P$($V$-nb) $=nRT$.
(B) For hydrogen gas value $ofZ=1$ at $P=0$ and it increase continuously on increasing pressure.
(C) $C{O}_2$ molecules have larger attractive forces, under normal conditions.
(D) $Z=\frac{P{V}_m}{RT}$ , at very large molar volume $Z\ne 1$.
