Vapor Pressure, Boiling Point, Phase Diagrams
Vapor pressure of liquid: example of equilibrium, equal and opposite rates of evaporation and condensation
B.p. temp. at which v.p. = external P.
Normal b.p. temp. at which v.p. = exactly 1 atm. or 760 torr.
Reduce pressure, reduce b.p. Vacuum distillation
Intermolecular forces and surface tension; viscosity
Enthalpy of vaporization > enthalpy of melting due to total breaking of intermolecular forces
Learn how to draw a general phase diagram
Significance of: triple point; critical point; difference between dense gas and liquid is absence of surface
Supercritical carbon dioxide useful solvent
