← ScienceWhich mechanism causes increased liquid H₂O surface tension, rather than vapor?
A)Intermolecular hydrogen increases near interface✓
B)Decreased potential energy vapor molecules
C)Increased kinetic water molecule energy
D)Covalent bonds saturate water surface
💡 Explanation
Intermolecular surface tension elevates because adhesion due to hydrogen bonding concentrates molecules, therefore increasing attraction at near the liquid-air interface, rather than if molecules had no polarity or only covalent connections.
