Formation of hydrogen bonds
WebCohesion: Hydrogen Bonds Make Water Sticky. Water has an amazing ability to adhere (stick) to itself and to other substances. 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 ... WebCohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress.Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their …
