Question

Which of the following is an example for fossil fuels?
A. Coal gas
B. Coke
C. Natural gas
D. Producer gas

Answer 1

Hint: Fossil fuels are made from plants and animals that decompose. In the Earth's surface, these oils contain carbon and hydrogen, which can be burned for oil.

Complete step by step answer:

Coal gas, gas mixture, primarily hydrogen, methane, and carbon monoxide created by the destructive distillation of bituminous coal and used as a fuel i.e. heating in the absence of air). Steam is also added to react with the hot coke, thus increasing the gas yield.
Coke, tough traces that exist after some forms of bituminous coals are heated out of contact with air to a high temperature before virtually all of the volatile materials have been extracted. The trace, including minimal quantities of hydrogen, nitrogen, sulphur, and oxygen, is mainly carbon. The mineral matter in the initial coal, chemically changed and decomposed during the process of coking, is still found in coke.
Natural gas, a highly flammable and colourless gaseous hydrocarbon composed mostly of methane and ethane. It is a type of petroleum that is generally associated with crude oil. Natural gas, a fossil fuel, is used for the generation of electricity, heating and cooking and as a fuel for many automobiles. In the manufacture of plastics, it is important as a chemical feedstock and is essential for a broad range of other chemical products, including fertilisers and dyes.
Producer gas, a combination of flammable gases (mainly carbon monoxide and hydrogen) and non-flammable gases (mainly nitrogen and carbon dioxide) formed by partial combustion in the air and steam atmosphere of carbonaceous substances commonly coal. The heating benefit of generating gas is smaller than that of other gaseous liquids, but it can be processed with relatively easy equipment; it is primarily used as fuel in large industrial furnaces.

Thus, the correct answer is option C.

Note: Scientists around the country and across the world are working to find solutions to issues with fossil energy so that adequate food and a sustainable climate are available to support human life and future events. They are still working to make it safer for coal burning and oil drilling. Greener methods have been used by academics to work out a way to consume fossil fuels while reducing their environmental effects. One option is to use more natural gas, which emits into the atmosphere 50 percent less carbon dioxide than coal does. The researchers also aim to extract carbon dioxide from the atmosphere and store a method called carbon capture and sequestration underground. By using carbon dioxide and sugar to produce green plastics, scientists are seeking something entirely new.
