Methodology of labrotary fractional distillation

Distillation involves 2 stages and both are physical state changes.
(1) In simple distillation the liquid or solution mixture is heated to boil and vaporise the most volatile component in the mixture (liquid ==> gas). The ant-bumping granules give a smoother boiling action for the distillation process.
(2) The vapour passes up from the flask and down into the condenser, where it is cooled by cold water and condenses (gas ==> liquid) back to a liquid (the distillate) which is collected in the flask.
(3) Any dissolved solids are left in solution because they have to high a boiling point to be distilled over e.g. the salts in sea water.
