•Distillation :The process of separating materials by successively heating to vaporizea portion and then cooling to liquefy a part of the vapor. Materials to be separatedmust differ in boiling point and/or relative volatility.
Evaporation BoilingOrdinary evaporation is a surface The boiling point is definedphenomenon - some molecules have as the temperature at whichenough kinetic energy to escape. If the the saturated vapor pressurecontainer is closed, an equilibrium is of a liquid is equal to thereached where an equal number of surrounding atmosphericmolecules return to the surface. The pressurepressure of this equilibrium is called thesaturation vapor pressure.
vapor pressure (true vapor pressure): The pressure exerted by the equilibriumvapor of a liquid when confined in a closed tank. Water boils at 100 °C Because vapor pressure of water = 1 atm @ 100 °C
