Question

Osmotic pressure can be increased by

• A. increasing the temperature of the solution.
• B. decreasing the temperature of the solution.
• C. increasing the volume of the vessel.
• D. diluting the solution.

Answer 1

Answer: (A)

Osmotic pressure is directly proportional to the temperature

$\because \pi=CRT$

where, C= concentration

R= gas constant

T= temperature

i.e. $\pi \propto T$, thus, on increasing the temperature, osmotic pressure also increases.
