surface adhesion

Surface adhesion refers to the process where different materials stick together at their contact point due to intermolecular forces, such as electrical attractions or chemical bonds. It explains why paint adheres to walls, glue sticks to surfaces, or water clings to a glass. These forces depend on the nature of the materials involved and how closely their molecules interact. Adhesion is essential in many everyday applications, ensuring materials stay together securely and perform their intended functions effectively.
