Question

Match the terms/statements in column A with those in column B.

Column 1	Column 2
Least inter molecular space	molecules
Chloroform	Sublimation
Boiling point of water	Liquid
Tiny particles	1000C
Camphor	Solid

Answer 1

Part A:

1. In solids, the particles are very closely packed and they cannot move from their respective position.
2. Intermolecular force is so high in solids, so the particles are very close and the inter molecular distance between particles is least in solids when compared to liquids and gases.

Thus, A - V

Part B:

1. Liquids have the intermolecular force of attraction much lesser than solids and as a result, they can flow easily.
2. Chloroform is an example of liquid.

Thus, B - III

Part C:

1. Boiling point is the temperature at which a liquid substance gets converted into vapour state by the supply of heat.
2. The temperature at which water changes to vapour is 100⁰C.

Thus, C - IV

Part D:

1. Matter is anything which has mass and can occupy space, also matter is made up of tiny particles.
2. The constituent tiny particles can either be atoms or molecules.

Thus, D - I

Part E:

1. Sublimation is the process in which a solid on heating directly gets converted into vapour state without passing through the liquid state.
2. Camphor and naphthalene are examples of the sublimation process.

Thus, E - II

Hence, the correct answer is A-V, B-III, C-IV, D-I, and E-II.
