Explanation:
Detailed explanation-1: -Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.
Detailed explanation-2: -Cohesion is the ability of like molecules to stick together. Water is strongly cohesive (it will form hydrogen bonds)
