melting point - wikipedia

the melting point (or rarely liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. at the melting point the solid and liquid phase exist in equilibrium. the melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kpa.
