How can the boiling point of a liquid be raised without adding a soluble impurity?

insoluble impurities donot raise the boiling point of a solution. it could be explained from raoults law that vapor pressure of the solution is affected by the partial vapour pressure of components in the solution. That is if the solute is not dissolved in a solution then how could it raise the boiling point. It wont affect its boiling point at all.

The boiling point of a liquid can be raised without adding a soluble impurity by increasing the external pressure. Higher pressure increases the boiling point of the liquid since it requires more energy (heat) for the liquid to change into vapor. ;

The boiling point of a liquid can be raised by increasing the pressure above it, which requires the vapor pressure to match this higher pressure before boiling occurs. Other methods include using controlled environments, such as autoclaves, to maintain a higher pressure. These techniques do not involve adding soluble impurities but rely on physical alterations of the conditions surrounding the liquid.
