Verified step by step guidance

Understand the key properties of water: Water molecules exhibit unique behaviors due to hydrogen bonding, including adhesion, cohesion, and surface tension.
Define adhesion: Adhesion refers to the ability of water molecules to stick to other substances or surfaces, such as glass, due to interactions between water molecules and the material's surface.
Differentiate adhesion from cohesion: Cohesion is the property that allows water molecules to stick to each other, while adhesion involves water molecules sticking to other surfaces.
Explain why adhesion is the correct answer: Water's adhesion property is responsible for its ability to stick to surfaces like glass. This occurs because the polar nature of water molecules interacts with the polar or charged molecules on the glass surface.
Clarify why other options are incorrect: Surface tension is related to cohesion and the formation of a 'skin' on water's surface, while hydrophobicity refers to substances that repel water, which is not relevant to water sticking to glass.
