Explanation:
Detailed explanation-1: -The hydrogen bonds between water molecules result in cohesion, adhesion, and surface tension.
Detailed explanation-2: -The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.
