Question

cohesion is the ability of water molecules to stick to... each other. metals. soil. glass.

Explanation:

Cohesion is a property of water molecules. By definition, cohesion refers to the attraction between like molecules. Water molecules are like each other. So, cohesion is the ability of water molecules to stick to each other. Metals, soil, and glass are different substances from water molecules. The attraction of water molecules to these (which is adhesion, a different property) is not cohesion.

Answer:

each other.
