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

	Column I		Column II
(A)	hydrogen gas (P = 200 atm, T = 273 K)	(P)	Compressibility factor $$\ne$$ 1
(B)	hydrogen gas (P $$\sim$$ 0, T = 273 K)	(Q)	attractive forces are dominant
(C)	CO$$_2$$ (P = 1 atm, T = 273 K)	(R)	PV = nRT
(D)	real gas with very large molar volume	(S)	$$P(V-nb)=nRT$$
