Answer: Option A. ->
Nylon
:
A, B, and C
The substances which are obtained from petroleum and natural gas are called petrochemicals. Petrochemicals are used in the manufacture of detergents, synthetic fibres, plastics etc.
Nylon, polyester and acrylic are examples of synthetic fibres that are manufactured using petrochemicals.

Answer: Option A. ->
Street Lighting
:
A
:
A
Coal gas is CO2 & CO. It is used as fuel and earlier in the year 1810 it was used for street lighting in London.
Whereas, mosquito repellent generally contains propane, petrol is used for the manufacture of paint and manure formation requires ammonia.
Answer: Option A. ->
Petroleum
:
A
:
A
Petroleum has great commercial importance, due to which it is also called the 'black gold'. Many useful substances are obtained from petroleum. These are termed as 'Petrochemicals'. These are used in the manufacture of detergents, fibres (polyester, nylon, acrylic, etc.), polythene and other manmade plastics.
Answer: Option B. ->
black gold
:
B
Many useful substances are obtained from petroleum and natural gas. These are termed as petrochemicals. These are used in the manufacture of detergents, fibres (polyester, nylon, acrylic etc.), polythene and other man-made plastics. Hydrogen gas obtained from natural gas, is used in the production of fertilisers (urea). Due to its great commercial importance, petroleum is also called ‘black gold’.

Answer: Option B. ->
Andhra Pradesh
:
A, B, C, and D
Natural gas is a fossil fuel formed million years ago along with petroleum by the dead microscopic organisms which got buried along with organic matter under the sand and mud. These organisms undergo anaerobic fermentation and get converted into natural gas. In India, natural gas is available in various parts of the country such as Assam, Gujarat, Andhra Pradesh, Maharashtra.

Answer: Option B. ->
False
:
B
Fossil fuels are formed when dead plants and animals undergo decomposition under high pressure and temperature for a long period of time.
Petroleum is formed when dead sea organisms undergo decomposition at high temperature and pressure. Petrol, diesel and kerosene are products that are obtained by refining petroleum. Hence, kerosene is also a fossil fuel.

Answer: Option D. ->
Carbon monoxide & nitrogen
:
D
:
D
When air is passed over red hot coke, incomplete combustion takes place resulting in the formation of CO (carbon monoxide) and the mixture of carbon monoxide and nitrogen (a major component of air) is called producer gas.
Answer: Option B. ->
False
:
B
Anthracite is the grade of coal that has the highest percentage of carbon followed by bituminous coal, lignite and peat. Higher the grade of a coal, lower is its ash content and thus greater combustibility.

Answer: Option A. ->
Naphthalene balls
:
A
:
A
Naphthalene or mothball is a white solid with a pungent odour derived from the distillation of coal tar. It sublimes into a pungent toxic smell which drives away insects and moths.
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.
