A student observes that a thin stream of water can momentarily bridge a small gap between two closely spaced glass surfaces. Water molecules are polar: oxygen has a partial negative charge and hydrogens have partial positive charges. Hydrogen bonds form between neighboring water molecules, creating cohesion, and water molecules can also form hydrogen bonds with polar groups on glass, producing adhesion. Together, these interactions can hold water in a continuous shape across a short distance, resisting separation. Which feature best explains the ability of water to bridge the gap between the glass surfaces?
