"explain the arrangement, movement and energy of the particles in each of the three states of matter: solid, liquid and gas"

Solids - Strong forces of attraction between particles - particles held close together in a fixed, regular arrangement. Particles don't have much energy so can only move about their fixed positions.

Liquids - Weaker forces of attraction between particles. Particles held close together, but can move past each other, and form irregular arrangements. Particles have more energy than a solid, so they move in random directions at a low speed.

Gases - Almost no forces of attraction between particles. Particles have lots of energy, so they are free to move. They travel in random directions at high speeds.
