Answer
| Property | Liquids | Gases |
|---|---|---|
| Arrangement of molecules | Molecules are not rigid and they are less closely packed | Molecules are very loosely packed |
| Inter-molecular separation | The inter-molecular spaces are more than solids | The inter-molecular space is very large as compared to solids and liquids |
| Inter-molecular force | The force is weak and molecules are free to move within the boundary of the container | The force is very weak so molecules are free to move anywhere |
| Kinetic energy of molecules | The kinetic energy is more than solids | Kinetic energy is the most in gases. |
