Kerosene and petrol are miscible liquids also the difference between their boiling point is more than 25 ºC so they can be separated by the method of distillation. Follow the steps given below (i) Take a mixture in the distillation flask fit it with the thermometer. (ii) Arrange the apparatus as shown in the given figure. (iii) Heat the mixture slowly keeping a close watch on thermometer. (iv) Since the petrol has lower boiling point starts vaporises and condenses in the condenser which is finally collected in the beaker.

Separating Kerosene and Petrol: A Detailed Explanation

Separating kerosene and petrol can be achieved through a process called fractional distillation. This method takes advantage of the different boiling points of these two substances to separate them effectively. Here is a step-by-step guide on how to separate kerosene and petrol:

1. Fractional Distillation Apparatus:
Set up a fractional distillation apparatus, which consists of a distillation flask, a fractionating column, a condenser, and collection flasks. The fractionating column contains several trays or plates to facilitate the separation process.

2. Heat the Mixture:
Pour the mixture of kerosene and petrol into the distillation flask. Apply heat to the flask using a Bunsen burner or a heating mantle. As the mixture is heated, the substances with lower boiling points will begin to vaporize first.

3. Vaporization and Condensation:
The vaporized substances pass through the fractionating column, where they condense on the trays or plates. The substances with lower boiling points, such as petrol, will condense at lower levels in the column, while those with higher boiling points, like kerosene, will condense at higher levels.

4. Collection of Petrol:
As the distillation process continues, the condensed petrol will collect in a separate flask connected to the fractionating column. Since petrol has a lower boiling point than kerosene, it will vaporize and condense at a lower position in the column.

5. Collection of Kerosene:
At a higher position in the column, kerosene will condense and collect in a separate flask. Its higher boiling point allows it to remain in vapor form for a longer duration before condensing.

6. Other Components:
Any remaining components that have higher boiling points than kerosene will remain in the distillation flask since they require higher temperatures to vaporize. These components can be removed and discarded once the process is complete.

7. Repeat if Necessary:
If there is still a mixture of petrol and kerosene left in the distillation flask, the process can be repeated to further separate the two substances.

By following the steps of fractional distillation, kerosene and petrol can be effectively separated from each other based on their different boiling points. This process allows for the extraction of pure kerosene and petrol, which can then be used for various purposes.
