Question

The three states of matter can be arranged in the decreasing order of interparticle forces as

• A. Solid$>$gas$>$liquid
• B. Liquid$>$gas$>$solid
• C. Solid$>$liquid$>$gas
• D. Gas$>$liquid$>$solid

Answer 1

The correct option is C

Solid$>$liquid$>$gas

Explanation for the correct option:

(c) Solid$>$liquid$>$gas:

1. The particle of matter exerts attractive forces upon another. These forces are called intermolecular forces or interparticle forces.
2. The particles of solids are closely packed and the empty spaces between the particles are very small.
3. Thus the intermolecular force of attraction is maximum in solids.
4. In liquids, the particles are loosely packed and the empty spaces between them are relatively large.
5. Due to loose packing, attractive forces between the particles of liquids are weaker than in solids.
6. Gases have a very weak intermolecular force between the particles as the particles are loosely packed.
7. Thus the decreasing order of interparticle forces is solid$>$liquid$>$gas.

Explanation for the incorrect options:

Since the correct decreasing order of interparticle forces is solid$>$liquid$>$gas thus options (a), (b) and (d) are incorrect.

Hence, option (c) is the correct option.
