The osmotic pressure of a solution increases,if:

Calculate the osmotic pressure of $0.03 \ mol$ of non-electrolyte solute dissolved in $0.1 \ dm^3$ of water at $300 \ K \ [R=0.0821 \ dm^3 \ atm \ mol^{-1} \ K^{-1}]$ (in $atm$)

The osmotic pressure of a dilute solution is $7 \times 10^5 \ Pa$ at $273 \ K$. Osmotic pressure of the same solution at $283 \ K$ is . . . . . . . $\times 10^4 \ Nm^{-2}$.

The osmotic pressure of a dilute solution is given by

$A$ solution is prepared by dissolving $0.6 \ g$ of urea (molar mass $= 60 \ g \ mol^{-1}$) and $1.8 \ g$ of glucose (molar mass $= 180 \ g \ mol^{-1}$) in $100 \ mL$ of water at $27 \ ^oC$. The osmotic pressure of the solution is : ............. $atm$ $(R = 0.08206 \ L \ atm \ K^{-1} \ mol^{-1})$

When kept in water,a raisin swells in size. Name and explain the phenomenon involved with the help of a diagram. Give three applications of the phenomenon.
