Question

Define melting point and boiling point

Answer 1

The boiling point is the temperature at which a material changes from a liquid to a gas (boils) while the 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.

Answer 2

Melting point is the state where a substance reaches the points where it can change from solid to liquid or if cooling process is happening, the change from liquid to solid.

Boiling point is the state where a substance reaches the points where it can change from liquid to gas or if cooling process is happening, the change from gas to liquid.
