MCQ

Two beakers $A$ and $B$ containing pure water and aqueous solution are shown. What will be observed gradually with passage of time ?

A
Level of water in beaker $A$ becomes lower than level of solution in beaker $B$
B
Level of water in beaker $A$ and level of solution in beaker $B$ remains constant
✓
Level of water in beaker $A$ increases and that of solution in beaker $B$ decreases
D
Level of both the beakers increases

✓

Answer

Correct option: C.

Level of water in beaker $A$ increases and that of solution in beaker $B$ decreases

c
$\mathrm{P}_{\mathrm{s}}=150-60 \mathrm{X}_{\mathrm{B}}$

For pure $\mathrm{B}, \mathrm{X}_{\mathrm{B}}=1$, $\mathrm{P}_{\mathrm{s}}=\mathrm{p}_{\mathrm{B}}^{o}=90$

For pure $\mathrm{A}, \mathrm{X}_{\mathrm{B}}=0$, $\mathrm{P}_{\mathrm{s}}=\mathrm{p}_{\mathrm{A}}^{o}=150$
