Answer 1

1. L=liquidity

L=liquidity P=petroleum

L=liquidity P=petroleum G=gas

2. An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils.

3. Products made from petrochemicals include such items as plastics, soaps and detergents, solvents, drugs, fertilizers, pesticides, explosives, synthetic fibres and rubbers, paints, epoxy resins, and flooring and insulating materials.

4.What is called as 'black gold'? (1) Hydrocarbon (2) Coal (3) petroleum (4) Ether. It is black in colour when crude oil is extracted from the soil. Because of its oil and worth, people call it gold. It's absolutely hard to find.

5.Coal, natural gas, and petroleum are all fossil fuels that formed under similar conditions. Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines.

6. Petrochemicals are chemical products derived from crude oil, although many of the same chemical compounds are also obtained from other fossil fuels such as coal and natural gas or from renewable sources such as corn, sugar cane, and other types of biomass.
