Answer» Match the transformations in Column-I with appropriate options in Column-II.

	Column I		Column II
(A)	$C O_{2} (s) \to C O_{2} (g)$	(p)	Phase transition
(B)	$C a C O_{3} (s) \to C a O (s) + C O_{2} (g)$	(q)	Allotropic change
(C)	$2 H \to H_{2} (g)$	(r)	$Δ H$ is positive
(D)	$P_{white, solid} \to P_{red, solid}$	(s)	$Δ S$ is positive
		(t)	$Δ S$ is negative
