Question

How does a glue and duct tape works?​

Answer 1

Answer:

Hi mate

Explanation:

The molecules of the adhesive stick to the molecules of the substrate, or adhere, but they also stick to each other, or cohere. If this weren't the case, the adhesive substance wouldn't hold together. The release coating prevents cohesion at the surface of the tape so it can be unrolled easily.

Answer 2

Answer:

• In adhesion, one type of molecule is sticking to another type of molecule; in cohesion, one type of molecule is sticking to itself. Tape uses both [source: Scientific American]. The molecules of the adhesive stick to the molecules of the substrate, or adhere, but they also stick to each other, or cohere.
