Updated On: Jun 17, 2022
- Enthalpy of physical adsorption is less compared to enthalpy of chemical adsorption
- Milk is an example for emulsion
- Physical adsorption increases with the increase in temperature
- Smoke is an aerosol
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Physical adsorption decreases with increase in temperature whereas chemisorption first increases and then decreases with increase in temperature.

Concepts Used:
Adsorption
Heinrich Kayser, the German physicist was the first to coin the term adsorption. Adsorption can be explained as a surface phenomenon where particles remain attached on the top of a material. Generally, it comprises the molecules, atoms, liquid, solid in a dissolved stage, even the ions of a gas that are attached to the surface. Much to our surprise, the consequence of surface energy i.e. adsorption is present in biological, physical, chemical, and natural systems and are used in many industrial applications.
