Question

Match the following.

Column I		Column II
(A)	Conversion of a liquid into solid is	(p)	Regelation
(B)	Conversion of a liquid into vapour is	(q)	Sublimation
(C)	Conversion of solid into vapour directly	(r)	Fusion
(D)	Melting of ice caused by pressure is	(s)	Vaporisation

• A. $A - r$, $B - q$, $C - p$, $D - s$
• B. $A - r$, $B - s$, $C - q$, $D - p$
• C. $A - r$, $B - s$, $C - p$, $D - q$
• D. $A - p$, $B - q$, $C - r$, $D - s$

Answer 1

Answer: (B)

Conversion of a liquid into solid is fusion.
$A \to r$
Conversion of a liquid into vapour is vaporisation.
$B \to s$
Conversion of a solid into vapour directly is sublimation.
$C \to q$
Melting of ice caused by pressure is regelation.
$D \to p$
