This equation tells us the relationship between pressure and the boiling point of the substance. When we put the isopropyl under vacuum conditions, let us say 67 mbar of vacuum, then the isopropyl alcohol will start boiling at 40 degrees celsius. Water at atmospheric conditions boils at 100 degrees celsius whereas when placed inside a vacuum chamber it will boil faster at 15 degrees celsius. Pressure Choose the actual unit of pressure: mbara psia mm Hg in Hg At lower pressures, a 10 C drop in boiling point can be observed for each halving of the pressure. Different types of alcohol have different boiling points, so this can be used to separate them from each other and from other organic compounds.
