Answer to Question #311520 in General Chemistry for Liskook

Question

Why is it that there is no temperature during melting and boiling when we know that there is?

Answer 1

Because changing a state of matter from a solid to a liquid or a liquid to a gas entails crossing the 'latent heat of fusion,' which causes a change in the intermolecular spacing of the molecules in the substance, the 'temperature of a substance' remains constant during melting and boiling.
