why does the temperature of a substance remain constant during its melting and boiling point?

Answered by crey

Latent heat of vapourisation is the required phenomenon

Stisti: Changing liquid to gas. When a liquid—such as water—is heated at a constant pressure, some of its molecules get enough KE to escape the liquid. ... Thus, more heat energy is needed to cause other molecules to escape. This keeps the liquid at a temperature slightly below that of the boiling point.

kaurkamboj227oyji40: thank u very much

Stisti: Most welcome

This is because during phase change ( change in state) , a certain amount of energy is absorbed to break the bonds between the matter so temp remains Constant.
