JEE MAIN - Chemistry (2020 - 7th January Evening Slot - No. 1)

Two open beakers one containing a solvent and the other containing a mixture of that solvent with a non voltatile solute are together selated in a container. Over time :
The volume of the solution increases and the volume of the solvent decreases.
The volume of solution does not change and the volume of the solvent decreases.
The volumer of the solution and the solvent does not change.
The volume of the solution decreases and the volume of the solvent increases.

Explanation

There will be lowering in vapour pressure for solution containing non-volatile solute. So, there will be transfer of solvent molecules from pure solvent to solution and hence, volume of beaker containing solvent (pure) will decrease and volume of beaker containing solution will increase.
