The following graph is obtained for vapour pressure (in atm) (on $y$-axis) and T (in K ) ( on $x$-axis) for aqueous urea, solution and water. What is the boiling point (in K) of urea solution? (Atmospheric pressure $=1 \mathrm{~atm})$
$\mathrm{T}_1$
$\mathrm{T}_2$
$\mathrm{T}_3$
$\mathrm{T}_4$
Solution
Boiling is the temperature at which vapour pressure eanal to the atmospheric pressure.
According to given graph, Solution of urea boil at $\mathrm{T}_3$ where boiling point down the line of 1.0 atm.
