What is the primary process involved in the adsorption of gases on solid surfaces?
Correct Answer: Van der Waals forces
- Step 1: Understand that adsorption is when gas molecules stick to a solid surface.
- Step 2: Know that this sticking happens because of forces between the gas molecules and the solid.
- Step 3: Learn that the main forces involved are called Van der Waals forces.
- Step 4: Recognize that Van der Waals forces are weak attractions between molecules.
- Step 5: Conclude that these weak forces allow gas molecules to adhere to the solid surface.
