The laboratory process of distillation does not involve changing a liquid to vapor changing a vapor to liquid liquids with different boiling points liquids with the same boiling points
liquids with same boiling point. laboratory application of distillation is basically separation of an impure liquid/mixed solvents with different boiling points.
A lab distillation doesn't involve liquids with the same boiling point. The point of a distillation is to separate two liquids with different boiling points by evaporating off the one with the lower boiling point, leaving the other liquid.
