WebThe melting point is the highest temperature at which crystallization may occur. It is also a temperature at which a solid (crystal) turns into a liquid. We say that such a body melts. The melting point is specific for a given substance. For example, the melting point of ice (frozen water) is 0 °C. The melting point depends on the pressure.
