Question

define melting point and boiling point.

Answer 1

The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure.

Answer 2

MELTING POINT :- It is the temperature at which a solid becomes liquid on absorbing heat .

BOILING POINT :- The temperature at which a liquid boils is called boiling point .
