A liquid cannot get any hotter when it boils because boiling by definition is the temperature at which the molecules of the substance are moving at such a high speed that they cannot stay in their liquid form - and they separate into a gas. Only in gasious form can the substance increase in temperature. So the boiling point is the maximum temperature of the liquid in its liquid form.

True. Boiling is the point at which liquid Water turns to gas. One reason why people put salt in water is because it raises the boiling point, which makes the water hotter, therefore food cooks faster

when liquid attains boiling point, heat energy is used to vaporise liquid into vapour so temperature of boiling liquid does not change.

True, the energy is being put into vaporizing the molecules and not changing the temperature.

the heat input all goes to the state-change reaction (chaninging form liquid to gas)
