Question

Match the columns

Column 1	Column 2
Expansion in length	Boiling
Expansion in volume	Evaporation
Expansion in area	Linear expansion
Rapid process	Cubical expansion
Surface phenomenon	Superficial expansion

Answer 1

Part A

1. Expansion in length is known as linear expansion.
2. Hence ( A) Expansion in length - (II) Linear expansion

Part B

1. Expansion in Volume is known as cubical expansion.
2. Hence (B) Expansion in volume - (IV) cubical expansion

Part C

1. Expansion in area is known as superficial expansion.
2. Hence (C) Expansion in area - (V) Superficial expansion

Part D

1. Boiling is bulk phenomenon.
2. It is rapid process.
3. Hence (D) Rapid process - (I) Boiling

Part E

1. Evaporation is Surface phenomenon.
2. Molecule at surface takes energy from surrounding.
3. Because of high energy they overcome the intermolecular force of attraction and leave the surface.
4. Hence (E) Surface phenomenon - (II) Evaporation
