Unformatted text preview: T How to calculate between phase changes. Intermolecular Forces Influenced Properties by intermolecular forces o Boiling point o Freezing point o Vapor pressure Types of intermolecular forces Hydrogen-bonding o Strongest force o Force between (H-O)(H-N)(H-F) Dipole-Dipole o Between All polar molecules. London dispersion forces o Between all molecules. o Temporary attraction. o Weakest force Viscosity The resistance to flow. intermolecular forces, viscosity size, viscosity Viscosity of a liquid decreases as temp. Increases because intermolecular forces become weaker. Surface tension Surface tension is the amount of energy to break the intermolecular force of a liquid. o intermolecular forces, surface tension. o temperature, surface tension. Know what crystal lattice looks like. Amorphous Randomly arranged Crystalline Well-ordered pattern....
