1.	In three beakers labelled as (A),(B) and (C ) , 100 mL of water, 100 mL of 1 M solution of glucose in water and 100 mL of 0.5 M solution of glucose in water are taken respectively and kept at same temperature . Which of the following statements is correct ?
Answer» VAPOUR pressure in all the three beakers in same Vapour pressure of beaker B is highest Vapour pressure of beaker C is HIGHER Vapour pressure of beaker B is LOWER than that of C and vapour pressure of beaker C is lower than that of A. Solution :The vapour pressure of pure solvent is ALWAYS higher than that of a solution which CONTAINS a non-volatile solute. The decrease of lowering in vapour pressure is related to the quantity of non-volatile solte present. Hence, vapour presures follow the order : `AgtCgtB`.
