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)

increasing the temperature of the solution.

Answer 2

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 pressurealso increases.
