The melting point of a compound is measured as a range of temperatures from where the solid phase transitions into the liquid phase. The upper limit of the range is the temperature where the first liquid drops are observed, and the lower limit of the range is the temperature where the solid phase has fully turned into liquid.
The melting point is.......
