Fractional distillation is a/an
Fractional distillation is a/an
Open in App
Solution
The correct option is B physical
Fractional distillation is the separation of a mixture into its components or fractions. This is mainly used to separate components of complex mixtures with small boiling point differences.
The mixture is heated and the vapours are passed along a tall fractionating column. The column has several condensers at different heights. It is hot at the bottom and cool at the top.
Components with high boiling points condense at the bottom, while with lower boiling points condense on the way to the top.
Petroleum industry rely on fractional distillation to obtain gasoline and many other chemicals from crude oil.
In this method only change in physical state of the components takes place, hence, it is a physical process.
