The beakers A and B containing pure water (A) and an aqueous solution of sugar (B) are placed in a closed glass container. The temperature of the container is kept constant. It is observed that

Options

A. level of water in beaker A decreases and that in beaker B increases with time
B. level of water in beakers A and B remains constant with time
C. level of water in beaker A increases and that in beaker B decreases with time
D. level of both the beakers decreases with time

Answer

A

Explanation

Rate of condensation remains the same for both the beakers. While rate of evaporation is more for beaker A (containing pure water) than for beaker B (containing sugar solution). As such equilibrium cannot be attained.
