← ScienceWhich mechanism enables surface water to persist as liquid?
A)Hydrogen bonding between water molecules✓
B)Covalent bonding within water molecules
C)Ionic bonding with dissolved minerals
D)Van der Waals forces water vapor
💡 Explanation
Hydrogen bonding creates intermolecular forces between water molecules due to hydrogen's partial positive charge. This enhances cohesion; therefore water remains liquid at higher temperatures, rather than vaporizing easily due to lower-strength London dispersion forces influencing small molecules.
