Answer 2

$\star \: \sf \green{Fractional \: Distillation}$

Fractional distillation is the process of separation of components of mixture on the basis of fractional differences in thier boiling points.

Fractional distillation is done when the difference in boiling points of the components of miscible liquids is less than 25°C.

In the process of fractional distillation, a fractional column is used along with retort or distillation flask.

Fractional column is a tube which contains glass beads,which facilitates surface for the vapour to cool and condense repeatedly.

$\star \: \sf \green{Example }$

Ethanol and water are separated from thiet mixture using fractional distillation. The boiling point of water is 100°C while the boiling point of ethanol is 78.4°C. Since the difference of thier boiling point is less than 25°C,thus they separated using fractional distillation.
