Some facts

  • The 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. The data provided in this calculator refers to the so-called normal pressure which is 1013,25 hPa.
