Answer 1

Explanation:

QUESTION:

why does the temperature of a substance remain constant during it's melting point or boiling point?

SOLUTION:

The temperature of a substance remains constant during at its melting or boiling point because all the heat energy supplied to the substance is absorbed by its particles and is used up in overcoming the forces of attraction between the particles and making them free to move apart. Therefore, it does not show any rise in temperature.

Answer 2

Answer:

The extra heat supplied is used in the melting of ice which is called the latent heat of fusion. Similarly, when a liquid starts boiling the temperature of the liquid does not change instead of a continuous supply of heat. ... That's why the temperature of a substance remains constant during its melting or boiling.
