As a substance reaches its boiling point it changes from a liquid to a gas. As this happens the bonds that are holding the molecules together break allowing the molecules to wander off on their own as a gas. 6. As a substance reaches its freezing point it turns from a liquid to a solid.
The closeness, arrangement and motion of the particles in a substance change when it changes state. Simple diagrams of particles in a solid, liquid and a gas are shown like this: The table summarises what happens to the particles in a substance when it gains energy, and it melts or boils (ie changes state): Evaporation happens below the boiling point of a liquid. When the liquid reaches its boiling point, evaporation happens very quickly and the liquid boils.
