The vapour pressure vs. temperature curve for a solution solvent system is shown below. The boiling point of…

We know that the temperature at which vapour pressure of a liquid becomes $1$ atm. is called the boiling point of the liquid.

From the figure, we can clearly see that Graph I is for pure solvent whereas graph II is for solution. Hence the boiling point of solvent and solution are $82°\mathrm{C}$ and $83°\mathrm{C}$ respectively.
