Which is a practical application of boiling-point elevation?

boiling sea water to recover the salt it contains.

adding antifreeze to water in a car radiator in summer to raise the boiling point.

burning coal to make the steam that powers a steam engine.

cooling a supersaturated sugar-and-water solution to form rock candy.

The correct answer would be the second option. A practical application of boiling point elevation would be adding antifreeze to water in a car radiator in summer to raise the boiling point. During summer, the water in the radiator would heat up faster due to the temperature of the environment, to prevent boiling of water, we add a solute to raise its boiling point. This phenomenon belongs to the colligative properties of solutions.
