उत्तर
The change of concentration at a surface brought about by the action of residual surface forces is known as adsorption.
Explanation:
It is a surface phenomenon where particles accumulate on the surface due to unbalanced molecular forces, resulting in a higher concentration at the surface than in the bulk of the solid or liquid. This occurs because the surface tends to satisfy these unbalanced forces by attracting atoms, molecules, or ions from other substances.
