melting point, temperature at which a substance changes its state from solid to liquid. Under standard atmospheric pressure different pure crystalline solids will each melt at a different specific temperature; thus melting point is a characteristic of a substance and can be used to identify it. Whe...
melt·ing point (mĕl′tĭng) The temperature at which a solid becomes a liquid. For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form. The melting point of ice is 32°F (0°C); that of iron is 2,797°F (1,535°C...
It has in general one value for the powdery metal as obtained by reduction of the oxide in hydrogen below the melting point of the metal, another for the metal in the state which it assumes spontaneously on freezing, and this latter value, in general, is modified by hammering, rolling, dr...
form of copper, which in pure copper is less stable than the f.c.c. structure, but which becomes more stable when sufficient solute is present to raise the electron concentration. From this point of view, which was already discussed by Rosenhain in 1926, the actual phase diagram may be ...
Use atomic or molecular properties to explain why calcium oxide has a much higher melting point (2580 degrees Celsius) than potassium fluoride (858 degrees Celsius). Why does methyl-4-hydroxybenzoate have a higher boiling point than methyl salicyclate?
