पर्याय
exhibit enormous surface area.
remain suspended in the dispersion medium.

are comparatively less in number.
उत्तर
The values of colligative properties of colloidal solution are of small order in comparison to those shown by true solutions of same concentration because of colloidal particles are comparatively less in number.
Explanation:
Collodial particles are bigger aggregative than the number of particles in a collodial solution. Hence, the values of colligative are of small order as compared to values shown by true solutions at same concencration.
