Ever wonder where a "fossil fuel" gets its name? Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure.

Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2. A gaseous byproduct referred to as coke oven gas (COG ...

Question 8: Explain the process of formation of petroleum. Answer: Petroleum is formed by the burial of aquatic plants and animals below the sea bed. The marine animals and plants died thousands of years ago and settled down in the bottom of the sea. In anaerobic conditions, microorganisms decompose this organic matter.

The process of coal formation is called carbonisation. The dead plants and vegetation due to temperature and high pressure over hundreds of years slowly turned into coal. This slow conversion of dead plants and forests into coal is called the process of carbonisation. The process is called so because coal largely contains carbon.

Solution. Verified by Toppr. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Some iron and steel making and other industrial processes burn coal. The extraction and use of coal cause many premature deaths and many illnesses.

Explanation: The coal is classified on the basis of its physical and chemical composition. The proximate and ultimate analyses are the common tests which are used to find the commercial value of the coal. The proximate analysis gives characteristics of coal such as percentage of moisture, ash and volatile matter.
