| Solids | Liquids | Gases |
| Highly Strong intermolecular forces between the molecules, leads to a definite volume in Solids. | The intermolecular forces are stronger than gases but weaker than solids. | The intermolecular forces are practically non-existent. Thus, there is no definite volume. |
| Solids have a definite shape to them. | Liquids do not have a definite shape. | Gases do not have a definite shape. |
| The intermolecular space between solids is absent. | The intermolecular space is moderate but present. | The intermolecular space is free-flowing and plenty. |
| They are incompressible. | Liquids cannot be compressed. | Gases can be compressed quite easily. |
