Question

The constituents of crude petroleum are separated by evaporation.

• A. True
• B. False

Answer 1

The correct option is B False

Fractional distillation
Principle: This process works on the basis of differences in the boiling points of different miscible liquids.

• Miscible liquids can be separated by the process of thermometer fractional distillation.
• The separation of a mixture of liquids by distillation is called fractional distillation.
• This is based on the principle that different liquids have different boiling points.
• Alcohol has a lower boiling point than water and therefore evaporates first.
• The vapor of alcohol gets condensed in the condenser and alcohol is collected in the flask.
• Petrol, diesel, and kerosene are obtained from crude petroleum by the process of fractional distillation.

Evaporation:

• The process by which a liquid is converted into its vapor state is called evaporation.
• Evaporation is used to separate a solid component from a homogeneous mixture of solids and liquids.
• For example, we can separate salt from a mixture of salt and water using evaporation. We heat the solution to a boiling point to obtain salt from salt water.

Therefore, The constituents of crude petroleum are separated by Fractional distillation. Hence, the given statement is false.
