Why does water have an unusually low vapor pressure for a liquid? the oxygen-hydrogen bond in a water molecule is unusually strong, which decreases the rate of evaporation. the oxygen-hydrogen bond in a water molecule is unusually weak, which increases the rate of evaporation. hydrogen bonding repels water molecules at the surface, increasing the rate of evaporation. hydrogen bonding attracts water molecules to one another and slows the rate of evaporation.
