Question

State how does osmotic pressure vary with temperature

Answer 1

it is directly proportional to temp
with increase in temp osmotic pressure increases and vice versa

Answer 2

The osmotic pressure increases with an increase in temperature and decreases with a decrease in temperature.

Explanation:

• The pressure which prevents the entry of the solvent into the solution through osmosis is called osmotic pressure.
• It is calculated through the following formula:

$\pi = CRT$

where,

$\pi$ - Osmotic pressure

C - Concentration of the solution

R - Gas constant

T - Temperature

• The above formula infers that osmotic pressure is directly proportional to factors such as concentration, gas constant and temperature.
• Thus it is inferred that as osmotic pressure is directly proportional to temperature increases with increase in temperature and decreases with decrease in temperature.
