3. Draw a labelled diagram of the set-up used in filtration.
4. Write the steps involved in distillation. How is distillation used in separating the constituents of a mixture ?​

Answer 1

2) The three useful products of crude petroleum are-

. Jet fuel

. Gasoline

. Diesel fuel

These products are obtained by the process of petroleum refining

4) The process of distillation are-

. The process begins with heating the liquid to it's boiling point.

. The liquid evaporates forming vapour.

. The vapour then cooled by passing the vapour drops through a pipe in low temperature.

. The vapour then condenses, forming a distillate.

QNo. 3 is given above

*4) Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation.
