Question

why does the temprature of substance remain constant during its melting or bowling pint
​

Answer 1

Answer:

latent heat of fusion

Explanation:

as the heat supplied is used to overcome the force of attraction of particles, so temperature remains constant, but changes after the conversion of the state of matter

Answer 2

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 to overcome force of attraction between particles of solid to change into liquid during melting and latent heat of vaporisation to overcome force of attraction between particles of liquid to change into vapours during boiling.

Therefore, temperature remains constant.
