Explanation: Which of the following scenarios is an example of cohesion?

Choose 1

(Choice A, Incorrect)

INCORRECT

Water molecules stick to the surface of a mirror.

This is an example of adhesion - the ability of water molecules to stick to other molecules.

(Choice B, Checked, Correct)

CORRECT (SELECTED)

Water molecules stick to one another and form a bead.

Cohesion is the ability of water molecules to stick to one another due to hydrogen bonding.

(Choice C, Incorrect)

INCORRECT

Water molecules stay on the tip of a pine needle because the water is attracted to the surface of the needle.

This is an example of adhesion - the ability of water molecules to stick to other molecules.

(Choice D, Incorrect)

INCORRECT

Water sticks to the walls of blood vessels.

This is an example of adhesion - the ability of water molecules to stick to other molecules.
