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. WebMelting point. Candidates should be familiar with determination of melting point and mixed melting point experimental procedures. Determination of the melting point can also give an indication of the purity of a compound, as the presence of impurities lowers the melting point and broadens its melting temperature range. Wales.
