(a) Used for road surfacing (iii) Bitumen The substance used for road surfacing is bitumen which is a black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation. (b) Natural gas (iv) CNG Natural gas is stored under high pressure is known as compressed natural gas, is an eco-friendly alternative to petrol. (c) Petroleum (i) Black gold Petroleum is also attributed as black gold which is a term applied to oil or petroleum, which is black when it comes out of the ground and is worth a great deal of money. As it is used in the manufacture of many useful products such as synthetic fibres and plastics. (d) Paraffin wax (ii) Vaseline and candles Paraffin wax is used to make vaseline and candles, also known as straight wax.

Match the items given in Column I with the items of Column II. Column I Column II (a) Coke (i) Fuel for home (b) Coal (ii) Produce more energy (c) Oil refinery (iii) Fractions of petroleum (d) Good fuels (iv) The Purest form of carbon (e) LPG (v) Barauni (f) Petrol and diesel (vi) Carbon

(a) Coke (iv) The Purest form of carbon Coke is almost considered as the purest form of carbon. It is obtained by strongly heating coal in absence of air. (b) Coal (vi) Carbon Coal is a hard, black combustible fossil fuel. Coal contains mostly carbon with variable amounts of other elements; chiefly hydrogen, sulphur, oxygen, and nitrogen. (c) Oil refinery (v) Barauni One of the oil refineries is Barauni refinery in the Bihar state of India was built in collaboration with the Soviet Union at a cost of Rs. 49 . 4 crores and went on stream in July 1964 . Here crude oil is transformed and refined into more useful products such as petroleum. (d) Good fuels (ii) Produce more energy Good fuels produce more energy and less pollution. One of the examples is natural gas. (e) LPG (i) Fuel for home LPG is attributed as fuel for home since it is used for cooking food in the kitchen. Liquefied petroleum gas is known as LPG. (f) Petrol and diesel (iii) Fractions of petroleum Petrol and diesel are fractions of petroleum which is a mixture of various constituents such as petroleum gas, petrol, diesel, lubricating oil, paraffin wax, etc. The process of separating the various constituents/ fractions of petroleum is known as refining.
