Vedclass · Answer

(B) The osmotic pressure $(\pi)$ of a solution is given by the formula: $\pi = CRT$,where $C$ is the molar concentration,$R$ is the gas constant,and $T$ is the temperature in Kelvin. Since $C$ and $R$ are constant,$\pi \propto T$. Initial temperature $T_1 = 37 + 273 = 310 \, K$. Final temperature $T_2 = 327 + 273 = 600 \, K$. The ratio of the osmotic pressures is $\frac{\pi_2}{\pi_1} = \frac{T_2}{T_1} = \frac{600}{310} \approx 1.935$. Looking at the options,the closest value is $2$.

When the temperature of a certain solution is increased from $37\, ^\circ C$ to $327\, ^\circ C$,how many times will the osmotic pressure change?
