Question

Why does the temperature of a substance change during melting point or boiling even when heat is being supplied to it continuosly?

Answer 1

hey mate here is your answer.....
hope it helps you friend ✌️✌️✌️✌️✌️

On heating a solid, its molecules absorb energy in the form of heat and their kinetic energy increases. As the kinetic energy increases, the temperature of the solid increases. ... At a particular temperature, the separation of the molecules increases by a large amount and the solid melts and converts into liquid.

Answer 2

Because it is superheated and in superheated condition it has high kinetic energy which lead to obsorption of heat.
