Question

Why does water have a high surface tension? (2 points) Group of answer choices The lengths of the bonds in water molecules can change. Water molecules contain 18 electrons. Hydrogen bonding keeps water molecules close together. Water is a liquid at room temperature.

Answer 1

Water's high surface tension is due to the hydrogen bonding in water molecules. Water also has an exceptionally high heat of vaporization. ... Water's heat of vaporization is 41 kJ/mol. Vapor pressure is inversely related to intermolecular forces, so those with stronger intermolecular forces have a lower vapor pressure.
