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.

The melting point and freezing point of water ideally are the same, especially if there are gas bubbles in water, but if the water is free of nucleating points, water can supercool all the way down to −42 °C (−43.6 °F, 231 K) before freezing. So, in some cases, the melting point of water is considerably higher than its freezing point.
The melting points of the lanthanide metals rapidly increase with increasing atomic number from 798 °C (1,468 °F) for cerium to 1,663 °C (3,025 °F) for lutetium (a doubling of the melting point temperatures), while the melting points of scandium and yttrium are…

Take the melting point of the two mixtures simultaneously. Quickly heat the samples to within 30°C of the approximate melting point you measured earlier. Then slow the heating rate increase to 1-2°C per minute. Record the melting point range for each mixture and identify your unknown compound.
Aug 18, 2019· The final value of the melting range is at the highest the melting point of the pure solid, but is often lower, reflecting the depressed melting point of the bulk solid. For example, a solid that is (20%) compound A and (80%) compound B would have a final melting temperature of point c …
