What is the boiling point of the solution? The boiling point of a solution, then, will be greater than the boiling point of the pure solvent because the solution (which has a lower vapor pressure) will need to be heated to a higher temperature in order for the vapor pressure to become equal to the external pressure (i.e., the boiling point).
How do you find the boiling point of a solution? mKb. Delta T refers to the boiling-point elevation, or how much greater the solution’s boiling point is than that of the pure solvent. The units are degrees Celsius. Kb is the molal boiling-point elevation constant.
Why is the boiling point of the solution? Boiling occurs when the vapor pressure of the liquid or solution is equal to the ambient pressure. Since the vapor pressure of the solution is less than the vapor pressure of the pure solvent, the temperature of the solution must be elevated above the boiling point of the solvent to allow the solution to boil.
What is the boiling point of a liquid solution? The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).

How does boiling water cool?
It is because when water is boiled with the effect of pressure only, then no external heat is supplied and the water is boiled in the cost of its own internal energy.
