Quizplus · Accepted Answer

The melting point is the temperature at which a solid substance changes to a liquid state. This occurs at the same temperature as the freezing point, which is the temperature at which a liquid changes to a solid state. On a phase diagram, the freezing/melting point is indicated by the line separating the solid and liquid phases.
