Question

multiple - choice question
what is cohesion?
water molecules sticking to surfaces.
the ability of water to dissolve other substances.
water molecules sticking to other water molecules.
the upward motion of water against gravity.

Explanation:

Cohesion is the property of like - molecules (in this case water molecules) sticking to each other due to intermolecular forces. Water molecules sticking to surfaces is adhesion, the ability to dissolve substances is solubility, and the upward motion of water against gravity is related to capillary action which is a result of both adhesion and cohesion.

Answer:

C. Water molecules sticking to other water molecules.
