Answer
As a liquid is heated at constant pressure, its temperature rises because the heat is used to increase the kinetic energy of the molecules inside the liquid. But after reaching the boiling point, the heat added is used to break the intermolecular forces of the liquid, and the liquid is converted to gas. Therefore, no further rise in temperature of the liquid can be induced by heating.
