The correct statement(s) about surface properties is (are)A. The critical temperature of ethane and nitrogen are 563K and 126K, respectively. The adsorption of ethane will more than that of nitrogen of sae amount of activated charcoal at a given temperatureB. Cloud is an emulsion type of colloid in which liquid is dispersed phase and gas is dispersion mediumC. Adsorption is accompanied by decreases in enthalpy and decrease in entropy of the systemD.

Answer» Correct Answer - A::C Higher the critical temperature, higher will be extent of adsorption. ltBrgt Cloud is an arosol, emulsions are liquid-liquid colloidal system. For adsorption `DeltaHimplies`negative:`DeltaSimplies`negative Brownian movementof colloidal particles depends on size off particles.
