Description : Why does the temperature of a substance remain constant during its melting point or boiling point? -Maths 9th
Last Answer : The extra heat supplied to the boiling water is used in the vaporization of a liquid, which is known as the latent heat of vaporization. That's why the temperature of a substance remains constant during its melting or boiling.
Last Answer : The temperature of a substance remains constant during melting and boiling points till the completion of melting and boiling. It is because substance makes use of latent heat of fusion ... between particles of liquid to change into vapours during boiling. Therefore, temperature remains constant.
