Question

Differentiate the three states of matter on the basis of intermolecular forces of attraction.

Answer 1

The intermolecular force of attraction:

• It is the force of attraction present between different molecules.
• It can be strong or weak depending on the type of particles.
• On the basis of intermolecular forces of attraction three states of matter can be differentiated as follow:

SOLID	LIQUID	GAS
1. Particles have a strong intermolecular force of attraction.	1. Particles have the less intermolecular force of attraction as compared to solids.	1. Particles have the least intermolecular force of attraction as compared to solids and liquids.
2. Due to strong intermolecular force of attraction between particles distance between particles is negligible.	2. Due to moderate intermolecular force of attraction the between particles distance between particles is more in comparison to solids.	2. Due to weak intermolecular force of attraction between particles distance between particles is more in comparison to solids and liquids.
3. Example: Sugar crystals	3. Example: Alcohol	3. Example: Nitrogen gas
