Which term describes the bond between dissimilar materials due to attractive forces?

• A. Corrosion
• B. Adhesion
• C. Solubility
• D. Flow

Answer: (B)

Adhesion is the attraction between unlike materials that makes them stick together. This describes the bond formed at the interface where two different substances meet, held together by attractive forces such as van der Waals interactions or hydrogen bonds. It explains why a glue can attach a material to another surface and why liquids can wet a solid. Corrosion refers to the chemical deterioration of a material, usually metal, due to reactions with its environment. Solubility is about a substance dissolving in a solvent. Flow describes the movement of a liquid. None of these capture the idea of two different materials sticking to each other.
