Solids- the intermolecular forces between the particles in solids are very strong that pack and arrange the particles in a fixed position.
Liquids- the intermolecular forces are quite weak but keep the liquid molecules in a fixed position, allowing them to freely move from one point to another.
Gases- there are insignificant intermolecular forces between molecules which keep the molecules widely separated.
