Intermolecular Forces Glossary

Temperature where vapor pressure equals atmospheric pressure.

Solution properties depending on solute particle count: BP elevation, FP depression, osmotic pressure.

T and P above which distinct liquid and gas phases do not exist.

IMF between permanent dipoles of polar molecules.

Strong dipole-dipole interaction involving H bonded to N, O, or F.

Attraction between ions and polar molecules; dominant in ionic solutions.

Weak IMFs from temporary dipoles; present in all molecules.

Pressure vs temperature plot showing phases and phase boundaries.

Tendency of liquid surface to minimize area due to inward IMF pull.

Unique conditions where all three phases coexist.

Number of particles a formula unit dissociates into in solution.

Pressure of vapor in dynamic equilibrium with liquid at a given temperature.

Measure of a fluid resistance to flow; increases with stronger IMFs.
