                  Crude oil (Petroleum)
Crude oil is a dark and sticky viscous liquid found in underground. It contains hydrocarbons such as alkanes, alkenes, etc. Natural gas is found together with crude oil. Natural gas consists mainly of methane. Crude oil is measured in barrels. 
1 barrel = 159 litres

      Fractional distillation of crude oil
 Fractional distillation is the process used to separate crude oil into its fractions.

                  Fractions of crude oil 
The fractions of crude oil are:
1. Petroleum gas 
2. Petrol 
3. Kerosene 
4. Diesel 
5. Lubricating oil 
6. Bitumen 
               Uses of crude oil 
1. Petroleum gas: Used as domestic fuel
2. Petrol: Used as fuel in motor vehicles
3. Kerosene: Used as fuel for heating and lighting
4. Diesel: Used as fuel in diesel engine
5. Lubricating oil: Used in making cream and hair-care products. Also as a lubricant
6. Bitumen: Used in road construction
