Which statement describes a change of state from solid to liquid?

Explanation:
Melting is the change of state from a solid to a liquid. When a solid is heated, its particles gain energy and vibrate more vigorously. At the melting point, the energy is enough to overcome enough of the forces holding the particles in fixed positions, allowing them to slide past one another and form a liquid that flows. This transition changes the state without changing the substance itself. Other state changes involve different directions of transformation: a solid becoming a gas is sublimation, a liquid becoming a gas is vaporization, and a liquid becoming a solid is freezing.
