Question

explain congruent and incongruent melting point.

Answer 1

Answer:

Explanation:

Congruent melting occurs during melting of a compound when the composition of the liquid that forms is the same as the composition of the solid. It can be contrasted with incongruent melting. ... Congruent melting point represents a definite temperature just like the melting points of pure components.

Incongruent melting occurs when a solid substance does not melt uniformly. During melting a new solid (of different composition) forms. For example, melting of orthoclase (KAlSi3O8) produces leucite (KAlSi2O6) in addition to a melt. ... Enstatite melts congruently between pressures of 2.5 and 5.5 kilobars.
