Explain why, there is no rise in temperature of a substance when it undergoes a change of state though heat is supplied continuously.

(a) Explain why there is no rise in temperature of a substance when it undergoes a change of state although it is still being heated. (b) Name one property which is shown by naphthalene and not by sodium chloride.

Why does the temperature remain constant during the boiling of water even though heat is supplied continuously ?

Why does the temperature remain constant during the melting of ice even though heat is supplied continuously ?

Why do substances undergo change in physical state ?

Heat changes the arrangement of particles in a substance when there is a change of state.

Whenever there is a change in the state of a substance, without change in temperature, then

"After the steady state, the temperature of a conductor does not rise, even though heat is supplied",. Why?

Explain the role of latent heat in the change of state of a substance.
