Which of the following forces is involved in physical adsorption?

a) Gravitational force

b) Magnetic force

c) Van der Waals force

d) Electromagnetic force

Expert Solution

Answer : c) Van der Waals force

Explanation :

In physical adsorption, the molecules of the adsorbate stick to the surface of the adsorbent due to very weak forces which is known as Van der Waals force.

Van der Waals force is similar to the forces that cause condensation of gas into liquid.

Van der Waals is weak as compared to gravitational force, Electromagnetic force and Magnetic force

c) Van Der Waals force

Recall that there are four fundamental forces: the gravitational force, the electromagnetic force, the weak nuclear force, and the strong nuclear force. Select any two of these forces and compare them. Consider their relative strengths, the range of distances over which they operate, and why they are important.
