1.	In the graph plotted between vapour pressure (V.P.) and temperature (T), A. PQ is the curve for solvent , XY is the curve of solution and `DeltaT` is depression in freezing pointB. PQ is the curve for solution. XY is the curve for solvent and `DeltaT` is elevation is boiling pointC. PQ is the curve for solvent, XY is the curve for solution and `DeltaT` is molal elevation in boiling pointD. PQ is the curve for solvent, XY is the curve for solution and `DeltaT` is elevation in boiling point
Answer» Correct Answer - D PQ corresponds to increase in vapour pressure of solvent with temperature and XY corresponds to increase in vapour pressure of solution with temperature . `DeltaT` is the elevation in boiling point of a solution.
