Solution

Solids
Liquids
Gases
1. The internuclear force of attraction holding together the particles of a solids is very strong. 1. The internuclear force of attraction holding together the particles of a liquid is weaker as compared to solids. 1. The internuclear force of attraction holding together the particles of a gas is weakest.
2. Due to strong internuclear force of attraction, the particles are tightly packed and hence there is very little inter-particle space inside the substance. Therefore, the compressibility of solids is negligible. 2. Due to weaker intermolecular force of attraction, there is some space between the particles, leads to some compressibility but it requires a high amount of pressure to compress them. 2. Due to weakest internuclear force of attraction, there is a large space between the particles and hence is highly compressible.
3. Solids have least compressibility. 3. More compressible than solid and less than gases. 3. Gases show maximum compressibility.
