Question

melting point and freezing points of substances are ​

Answer 1

Melting  point is the temperature at which a substance starts to melt.

Freezing point of a substance is the temperature at which a substance starts freezing.

Answer 2

The melting temperature of a solid is generally considered to be the same as the freezing point of the corresponding liquid; because a liquid may freeze in different crystal systems and because impurities lower the freezing point, however, the actual freezing point may not be the same as the melting point. Thus, for characterizing a substance, the melting point is preferred. See also melting.
