Coal is a solid fossil fuel created from vegetation that was squeezed by pressure for millions of years. During the first part of the Cenozoic Era, which began about 65 million years ago, the last of the seas that had covered North Dakota drained away. Layer after layer of rotted trees and other vegetation piled up in swamps over millions of ...

Coal is a combustible black or brownishblack sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Layers of dirt and rock covered the ...

Petroleum is a mixture of many substances such as gas, petrol, diesel, kerosene, lubricating oil, paraffin wax, etc. As these constituents serve different purposes, it is important to separate them, or in other words, refine the crude oil. This process of separation of various constituents of petroleum is called petroleum refining.

The arc process, however, was costly and inherently inefficient in its use of energy, and it was soon abandoned for better processes. One such method used the reaction of nitrogen with calcium carbide at high temperatures to form calcium cyanamide, which hydrolyzes to ammonia and cyanamide process was utilized on a large scale by several countries before and during World War I, but it ...

Answer. Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial ...

Coal formed millions of years ago when the earth was covered with huge swampy forests where plants giant ferns, reeds and mosses grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.

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.

Uses of Coal. It is mainly used to generate heat and electricity. It is used in s and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.

When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas. Coal tar is a thick black liquid that is a byproduct of the destructive distillation of coal. It contains benzene ...

Solution. Verified by Toppr. The process of fusion of male gamete with the gamete to form the diploid zygote (2n) is known as fertilisation. The fusion of one male gamete with egg and that of another male gamete with a secondary nucleus is called double fertilisation. It is the characteristic feature of only angiosperms.

Fossil fuels are made from decomposing plants and animals. These fuels are found in Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers. More than 50 percent of a piece of coal's ...

Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization . Carbonization differs from coalification in that it occurs much faster, due to its reaction rate being faster by many orders of magnitude.

Description: Coalification is a geological process of formation of materials with increasing content of the element carbon from organic materials that occurs in a first, biological stage into peats, followed by a gradual transformation into coal by action of moderate temperature (about 500 K) and high pressure in a geochemical stage.

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbonbased material approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coalbearing rock units appeared about 290360 million years ago, at a time known as the Carboniferous or "coalbearing" Period.

Also known as "soft coal", bituminous coal is the type found in Cape Breton and is our most abundant fuel. It is greatly used in industry as a source of heat energy. Anthracite, the fourth stage in coal formation, is also known as "hard coal" because it is hard and has a high lustre. It appears to have been formed as a result of ...

Solution. Fossil fuels are formed by decomposing dead and decaying plant or animal matter underground for millions of years. When any plant or animal dies, soil bacteria start decomposing the matter which was gradually buried by the layers of rock in the earth's crust which increases the heat and pressure inside, and as a result of heat, fossil ...

Knowing the physical properties of coal is important in the preparation and use of coal. For example, coal density ranges from about to about megagrams per cubic metre, or grams per cubic centimeter. Coal is slightly denser than water and significantly less dense than most rocks and mineral matter.

In the process of coal formation, first, the hydrogen is removed, then the nitrogen, and then the carbon. Carbon is most stable amongst hydrogen, nitrogen, and carbon. When the biochemical decomposition of vegetal matter happens, the result is carbon enrichment. Mode of Deposition of Coal. Let us understand the process of coal deposition in detail.

The most favorable conditions for the formation of coal occurred 360 million to 290 million years ago, during the Carboniferous ("coalbearing") Period. However, lesser amounts continued to form in some parts of the Earth during all subsequent periods, in particular the Permian (290 million to 250 million years ago), and throughout the ...

Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion.
