Document Summary

State of substance (phase) depends on the balance between kinetic energy of the particles and intermolecular forces. Liquids and solids are the condensed phases. Strength of imfs generally decreases as temperature increases. Ease w/ which a molecule produces a dipole moment. Increases as number of electrons in an atom/molecule increase. Strength of dispersion forces increases with increasing mw. For molecules of approx. same mass and size, strength of attractions increase with increasing polarity. Contribute more than any other molecular force. When molecules of 2 substances are different in mw and no h-bonding . Dispersion forces determines which substance has stronger imfs. Causes differences in bp when molecules of 2 different substances are about the same size and mass. Increases as mw increases and/or as strength of imfs increases. The energy required to increase the surface area of a liquid by a unit amount. Bind molecules of a substance to one another.
