hi guys,
Can anyone tell me what Fractional Distillation is?
no copy - pasting from the internet please
it would be really helpful and kind if you did so and you would earn points

Fractional distillation is used to separate two miscible liquids whose difference between the boiling point is less than 25°C.
Hope it helps uhh✌✌✌
FRACTIONAL DISTILLATION:-
✳Fractional distillation is the method used for the separation of a mixture containing two miscible liquids differing in boiling points by means of distillation using a fractionating column. In case the difference in the boiling points of the liquids is less than 25K temperature, we use the fractional distillation method.
✳The apparatus is almost the same as used in distillation. The only difference is that a fractioning column is fitted in between the distillation flask and the condenser.
✳ A simple fractioning column is made up of a tube packed with glass beads. The beads provide the surface for the vapours to cool and condense again and again.
✳The fractioning columns obstruct the smooth upward flow of vapours.
✳Common uses of fractional distillation include the production of distilled water, and gasoline from crude oil.
