Document Summary
Phase temperature (celsius) density (@ 1 atm ; g/cm3) 19. 6: measure of the average kinetic energy of the molecules. Solids and liquids are not easily compressed. Strength of force dependent on structure and shape of the particles. At room temperature: moderate strong = liquid or solid, high melting and boiling points, weak = gas, low melting and boiling points. Coulomb"s law: e = (1/4 e0)(q1q2/r, e is more negative as distance increases and as the magnitude of the charge increases, the more negative e, the more favorable stable the interaction. Intermolecular forces are always weaker than a bonding interaction: bonding interaction: proton and electron interaction at very small distances, intermolecular forces are smaller charges at greater distances. Intermolecular forces: dispersion forces (or london dispersion, dipole dipole forces, hydrogen bonding, ion dipole forces. 165: shape of molecule affects strength of dispersion forces, more area of interaction, more dipole movement, smaller area, larger the force.
