Answer 1

Explanation:

Boiling and boiling point :-

$\implies$ Boiling is the rapid vaporization process of a liquid.

$\implies$ The boiling point is the amount or value of temperature at which the vapor pressure of a liquid becomes equal to the external pressure that is which surrounds the liquid.

$\implies$ The boiling point of a liquid depends on atmospheric pressure or external pressure.

$\implies$ At sea level water boils at 100° C .

$\implies$ The boiling point of a liquid varies according to the applied pressure.

Melting and melting point :-

$\implies$ Melting is a physical process that results in the phase transition that is the substance changes its state from solid to liquid.

$\implies$ Melting point is the amount or value of temperature at which melting occurs.

$\implies$ The melting point of a substance is the temperature at which it changes its state.

$\implies$ Equilibrium is maintained at this point of the solid and liquid forms of a pure substance.

$\implies$ In increase in the force of attraction between the molecules can increase the melting point.

Answer 2

Answer:

Boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature. ...

The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
