Which of the following is an example of physisorption? (2021) 2021

Step 1: Understand what physisorption is. It is a type of adsorption that occurs due to weak forces called Van der Waals forces.
Step 2: Identify examples of physisorption. Look for processes where molecules stick to a surface without forming strong chemical bonds.
Step 3: Consider the example of water being adsorbed on silica gel. This is a common example of physisorption because the interaction is weak.
Step 4: Confirm that the example fits the definition of physisorption, which it does due to the weak forces involved.
