Answer: Option B. -> Petroleum
:
B
Petroleum or crude oil is anaturally occurring liquidfound deep inside the Earth, which is commonly refined into various types offuels. Components of petroleum are separated using a technique calledfractional distillation. Petrol, diesel, kerosene are few of the many components of petroleum.

Answer: Option C. -> Peat
:
C
Coal is formed when organic material is buried under sediment and exposed to high temperature and pressure for millions of years. The formation of coal takes place in four stages: peat, lignite, bituminous and anthracite coal. Peat is a heterogeneous mixture of more or less decomposed plant material that is accumulated in water, in the absence of air (anaerobic conditions). Peat is the primitive form of coal. The carbon content is least in peat.

Answer: Option B. -> petrochemicals
:
B
Petrochemicals are the chemical compounds derived from petroleum and natural gas. Products such as gasoline, fertilisers, cosmetics, etc. are products made from or with the aid of petrochemicals.

Answer: Option D. -> Petroleum
:
D
Petroleum is used as a solvent in dry cleaning industry due to its high degreasing ability, i.e., it can easily remove stains from clothes. It is one among the three commonly used solvents used in this industry and has been used since ancient times.

Answer: Option B. -> Coke
:
B
Coke is a tough, porous and black substance. It is almost a pure form of carbon. It is used in the manufacture of steel and also in the extraction of many metals.

Answer: Option B. -> Coal tar
:
B
Coal tar is a thick black liquid formed during the industrial processing of coal. It has an unpleasant odour and has high viscosity. It is used to manufacture various substances like synthetic dyes, paints, drugs and etc.

Answer: Option A. -> Anthracite
:
A
Different types of coal have different carbon content.
:
A
Different types of coal have different carbon content.
- Anthracite has the highest carbon content,between 92% to 98% and is often referred to as hard coal for this reason.
- Bituminous coal has a carbon content between 77% to 87%.
- Lignite has acarbon content between 60% to 70%.
- Peat has thelowest carbon content, less than 60%.
Answer: Option D. -> carbonisation
:
D
Plants contain mainly carbon, which gets converted into coal. Hence, the slow process of conversion of dead vegetation into coal is called carbonisation.

Answer: Option A. -> True
:
A
Crude oil or petroleum has components like petrol, diesel, kerosene, etc. These products have different boiling points which are useful in separating them through fractional distillation.

Answer: Option A. -> Coke
:
A
Coke is produced by baking coal in a heated oven. It is a fuel with high carbon content, generally used in the extraction of metals, manufacture of graphite, as a household fuel etc. Its price in the market depends upon the amount of ash and sulphur content present in it.
