Which of the following is not correct?

Options

A. Enthalpy of physical adsorption is less compared to enthalpy of chemical adsorption
B. Milk is an example of emulsion
C. Physical adsorption increases with the increase in temperature
D. Smoke is an aerosol

Explanation

Physical adsorption decreases with increase of temperature. Enthalpy of physical adsorption is low (20 – 40 kJ mol–1) compared to chemical adsorption (40 – 400 kJ mol–1).Milk is an oil in water type emulsion. Smoke is an aerosol because in smoke, gas is dispersion medium.
