Which of the following is NOT a type of adhesion?

• A. Mechanical adhesion
• B. Cohesive adhesion
• C. Chemical adhesion
• D. Dispersive adhesion

Answer: (B)

Cohesive adhesion is the term often used to describe the intermolecular forces that act between like molecules or particles, resulting in attraction within a single material. This contrasts with adhesion, which specifically refers to the attraction between different substances. The other types of adhesion - mechanical, chemical, and dispersive - each refer to distinct ways materials can bond or stick to one another. Mechanical adhesion involves physical interlocking of surfaces, chemical adhesion refers to the formation of chemical bonds between different materials, and dispersive adhesion pertains to the attraction caused by van der Waals forces between molecules. Therefore, selecting cohesive adhesion as the answer aligns with the understanding that it does not describe a process wherein two different materials adhere to each other, which is the primary focus of the other options.
