The reason for the use of finely powdered sample for determination of melting point should be explained. Concept introduction: Temperature at which an element changes from the solid state to the liquid state is known as melting point or sometimes liquefaction point. At the melting point, both solid and liquid phase coexist in equilibrium. It depends on the pressure and is normally defined at the standard pressure ( 1 atm ) .
