Melting

In physics, melting is the process of heating a solid substance to a point (called melting point) where it turns liquid. An object, which has melted, is molten. Freezing is the opposite of melting. It is the process of turning a liquid to a solid. Consequently the freezing point is the same temperature as the melting point.See phase article for more detail.
