Explanation:
▪ In water molecule, the oxygen atom carries a charge of partial negative charge, while the hydrogen atoms carries a charge of partial positive charge.
▪ Hydrogen bonding between water molecules is responsible for its high surface tension, low vapor pressure.
▪ When many water molecules form hydrogen bonds with other water molecules, they form a lattice of water molecules, which is very strong and flexible. Due to this there is high surface tension in the water molecules.
▪ Surface tension is what allows water striders to move across the surface of water.
▪ Vapor pressure is inversely related to intermolecular forces, so those with stronger intermolecular forces have a lower vapor pressure.
Answer:
i think the high surface tension is the oxygen atom acquires a partial negative charge, while the hydrogen atoms acquire partial positive charges.
Hydrogen bonding between water molecules is responsible for its high surface tension, low vapor pressure, and high melting and boiling points relative to other molecular substances with similar molar masses.
