Question

Explain why? The temperature does not rise during the process of melting or boiling through heat energy is constantly supplied

Answer 1

Answer:

Use latent heat concept here.

Explanation:

well the heat is constantly being used in changing the state of the material instead of changing its internal energy. the heat increases the potential energy of material by increasing the seperation between atoms instead of changing the kinetic energy of atoms due to which the temperature does not rise.

Answer 2

Answer:

the extra amount of heat is used up to breakup the molecular bonding during the process of boiling and evaporation

in simple this is known as the latent heat of vapourisation
