Which term describes the attraction of similar molecules?

Explanation:
Cohesion is the attraction among the same kind of molecules. In water, hydrogen bonds form between neighboring water molecules, pulling them toward each other and causing droplets to hold together and surface tension to arise. This tendency for like molecules to stick to one another is what cohesion describes. By contrast, adhesion is the attraction between different substances (like water sticking to a glass surface), metabolism refers to the chemical reactions inside organisms, and a law isn't about molecular interactions.
