State the type of colloid, dispersed phase, and dispersion medium in smoke and butter.

Select the incorrect common poperty of smoke and fog.

A solution in which no more solute can be dissolved in a definite amount of solvent

Pratiksha dissolved $105 \mathrm{g}$ of copper sulphate in $250 \mathrm{g}$ of water at $298 \mathrm{K}$. She stirred the solution thoroughly and after filtering it $25 \mathrm{g}$ of copper sulphate was obtained as the residue. In order to dissolve the obtained residue in the above solution at the same temperature, the amount of water that should be added by her will be
