Free Adhesives MCQs with Answers
4 Adhesives MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Adhesives are substances that join surfaces through bonding, wetting and hardening, and may be natural or synthetic. The topic covers starch, dextrin, casein, animal glue, rubber-based adhesives and polymeric resins, together with the effects of viscosity, setting time, temperature, moisture and surface condition on adhesive strength.

- A. melting the two surfaces together
- B. forming intermolecular forces or chemical bonds with both surfaces while cohering strongly within itself
- C. removing all air from between the surfaces only
- D. converting one surface into the other
Explanation: A good adhesive must both adhere, sticking to each surface, and cohere, holding together internally, and it usually starts as a liquid so…
Correct answer: forming intermolecular forces or chemical bonds with both surfaces while cohering strongly within itself- A. one tube contains the solvent that evaporates
- B. the two components are the same substance at different concentrations
- C. mixing lowers the temperature of the joint
- D. the resin and the hardener react together to form cross links, setting the adhesive
Explanation: Setting is a chemical reaction between the resin and a hardener that builds a rigid cross linked network, so the two must be kept apart…
Correct answer: the resin and the hardener react together to form cross links, setting the adhesive- A. cooling and solidifying, with no chemical change
- B. reacting chemically with the surface
- C. absorbing water from the air
- D. releasing carbon dioxide
Explanation: The adhesive is applied molten, flows into the surface irregularities and then simply freezes as it cools, so the change is physical and…
Correct answer: cooling and solidifying, with no chemical change- A. Triggers hydration
- B. Triggers hydrolysis
- C. Prevents rapid hardening
- D. all of the above
Explanation: About 2% gypsum is added to cement to react with the highly reactive aluminate component and control the setting time, thereby preventing…
