Matter changes from one state to another when matter it is either heated or cooled and the energy within the matter increases. When a solid changes to gas form, the intermolecular force of attraction decreases and the distance between the molecules increases. The closeness, arrangement and motion of the particles in a substance change when it changes state. When a substance is heated, its internal energy increases: the movement of its particles increases. bonds between particles break when a substance melts or evaporates, or sublimes to form a gas from a solid.
