Question

Define boiling point and melting point?

Answer 1

Boiling point- The temperature at which water starts boiling and gets converted into vapour state is called it's boiling point.

Melting point- The temperature at which the water changes from solid to liquid state at room temperature under atmospheric pressure is called it's melting point.

Answer 2

The boiling point is the temperature at which a material changes from a liquid to a gas (boils).
Whereas
melting point is the temperature at which a material changes from a solid to a liquid (melts).

Keep in mind that a material's melting point is the same as its freezing point.
