Answer Details
A mixture of kerosene and diesel oil can be separated by distillation. This is because the two liquids have different boiling points, and thus can be separated by heating the mixture to a temperature at which one of the liquids boils but the other remains a liquid. The vapor of the boiling liquid can then be collected and condensed back into a liquid, leaving the other liquid behind. In this case, kerosene has a lower boiling point than diesel oil, so heating the mixture will cause the kerosene to vaporize and be collected separately.
