Cloud is an emulsion type of colloid in which liquid is dispersed phase and gas is dispersion medium.

Adsorption is accompanied by decrease in enthalpy and decrease in entropy of the system.

Brownian motion of colloidal particles does not depend on the size of the particles but depends on viscosity of the solution.

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION.

(a,c) ⇒ Higher the critical temperature, higher will be extent of adsorption.

⇒ Cloud is an arosol, imulsions are liquid-liquid colloidal system.

⇒ For adsorption Δ H ⇒ negative : Δ S ⇒ negative

⇒ Brownian movement of colloidal particals depends on size of particles.
