Properties |
Solids |
Liquids |
Gases |
Shape |
Definite shape (intermolecular forces are very strong) |
Do not have a definite shape, takes the shape of the container in which they are kept. |
No definite shape (weak intermolecular forces) |
Volume |
Definite volume (The spaces between the particles are fixed.) |
Definite volume (The space between the particles is slightly more as compared to the solids, but still very less as compared to the gases. The particles of liquid can slip and slide over each other.) |
No definite volume(The spaces between the particles are not fixed.) |
Compressibility |
Negligible |
Negligible |
High |
Diffusion |
Can diffuse into liquids |
Diffusion is higher than solids. |
Highly diffusible (rate of diffusion is highest in gases). |
Fluidity or rigidity |
Very rigid and cannot flow from one place to another. |
Less rigid and can easily flow. Liquids show a property called viscosity. More viscous liquids flow more slowly, while less viscous liquids flow easily. |
No rigidity and can flow easily. |
