    Distillation is a process that can be used to separate a pure liquid from a mixture of liquids. It works when the liquids have different boiling points. Distillation is commonly used to separate ethanol - the alcohol in alcoholic drinks - from water.

    Step 1 - water and ethanol solution are heated
    Step 2 - the ethanol evaporates first, cools, then condensesStep 3 - the water left evaporates, cools, then condenses because ... The mixture is heated in a flask. Ethanol has a lower boiling point than water so it evaporates first. The ethanol vapour is then cooled and condensed inside the condenser to form a pure liquid. The thermometer shows the boiling point of the pure ethanol liquid. When all the ethanol has evaporated from the solution, the temperature rises and the water evaporates.
    In summary its because the mixture has different boiling points
