Question

Differentiate between solids, liquids and gases: On the basis of space.

Answer 1

Intermolecular space:

• It is the space present between different molecules.
• On the basis of intermolecular space three states of matter can be differentiated as follow:

SOLID	LIQUID	GAS
1. Particles have strong intermolecular force of attraction.	1. Particles have less intermolecular force of attraction as compared to solids.	1. Particles have very less intermolecular force of attraction as compared to solids and liquids.
2. Due to the strong intermolecular force of attraction between particles distance between particles is negligible.	2. Due to moderate intermolecular force of attraction 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: $\mathrm{NaCl}$ (Sodium chloride) crystals	3. Example: Water	3. Example: Nitrogen gas $\left({\mathrm{N}}_2\right)$
