The correct order of the strength of the forces between particles of different physical states is:
A. solids > liquids > gases
In solids, the particles are held closely together by strong intermolecular forces, resulting in a fixed shape and volume. In liquids, the intermolecular forces are weaker than in solids, allowing particles to slide past each other, giving liquids a definite volume but not a fixed shape. In gases, the intermolecular forces are very weak, allowing particles to spread out and fill the available space, leading to no fixed shape or volume.
