Document Summary
Amorphous: the atoms or molecules that compose a solid have no long-range order. Dispersion force: intermolecular forces present in all molecules and atoms; is the result of fluctuations in the electron distribution within molecules or atoms. Permanent dipole: positive end of one of these dipoles attracts the negative end of another; this attraction is the dipole dipole force. Miscibility: the ability to mix without separating into two states. Hydrogen bond: a strong attraction between the h atom on one molecule and the f, o, or. Surface tension: the energy required to increase the surface area by a unit amount. Viscosity: the resistance of a liquid to flow. Capillary action: the ability of a liquid to flow against gravity up a narrow tube. Vapor pressure: the pressure of a gas in dynamic equilibrium with its liquid. Boiling point: the temperature at which the liquid"s vapor pres sure equals the external pressure; leads to vaporization.
