Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowishblack liquid mixture of mainly hydrocarbons, and is found in geological name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil.. Petroleum is primarily recovered by oil drilling. ...
Coal oil is made by heating cannel coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes.
The process of conversion of this vegetation or plants into coal is called carbonization. 7. The plants buried under the soil undergo carbonization and change into coal. 8. Coal burns and produces mainly carbon dioxide when heated in the presence of the air. Fig: Formation of Coal Destructive Distillation of Coal

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 ...
The three laws of conservation of energy are as follows: 1) Energy cannot be created or destroyed, only transformed from one form to another. 2) The total amount of energy in the universe is constant. 3) Energy can neither be created nor destroyed; it can only be converted from one form to another.
Coal Production, Marketing Distribution 55 Chapter8 Coal Conservation, Research Development Coal Conservation Conservation of Coal is an important area particularly when our coal reserves are finite. The aspect of conservation of coal is taken into account right from the planning stage and maximum recovery is ensured
Question 2: Is coal a natural resource? Answer: Yes, coal is a natural resource since it is made up of dead and rotting vegetation and plants that have been buried for millions of years at high temperatures and pressures. Question 3: Describe the Process of Petroleum Refinement. Answer: The refining of oil is a highly mechanized process.
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. Coal is also called black gold.
It is the coal with the lowest carbon content. The carbon content is only about 6070 %. It is formed during the younger stages of coal formation and thus has a lower carbon content. Due to the less amount of carbon, it is not fully black in colour and is somewhat brown. Lignite is used in electricity generation and in fertilizer production.
Coal and petroleum are formed from the dead remains of living organisms that is why they are called fossils fuels. Question 5. Give two characteristics of coal. Answer: Coal is hard and is of black in colour. Question 6. Define destructive distillation. Name the residue formed by destructive distillation of coal.
The process of conversion of wood into coal is called carbonisation. Page No 77: Question 4: ... Process of fractional distillation of crude oil is as follows: ... Conservation of resources means not only avoiding their wasteful use but also maintaining their quality. It can also be defined as restoring, protecting and maintaining the natural ...
Law of Conservation of Mass. The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.
Coal is a nonclastic sedimentary are the fossilized remains of plants and are in flammable black and brownishblack tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal on the type of plant material, varying degrees of ...
Question 18 (a) The slow process of conversion of dead vegetation into coal is called ___. (b) Coal and petroleum are formed from the dead remains of organisms and are known as ___. (c) The black thick liquid with ___ smell is known as coal tar (d) During the processing of coal to get coke, coal tar and ___ are also obtained. (e) The process of separating the various constituents of petroleum ...
Coal is formed from the remains of plants, by a process called coalification. The whole process starts with the remains of dead plants, which must be buried in an oxygenpoor or oxygenfree environment, to avoid complete decomposition. Usually, these are swamptype environments. The coalification process takes place over millions of years.
The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel. Coal, which is mainly carbon, on heating produces mainly carbon dioxide gas and a lot. of heat energy.
Coal Geology. Coal is a combustible sedimentary rock formed from ancient vegetation which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time period. This process is commonly called 'coalification'. Coal occurs as layers or seams, ranging in ...

oxidation. D. reduction. Medium. Open in App. Solution. Verified by Toppr. Correct option is A) The slow process of conversion of dead vegetation into coal is called Carbonization.
Ans. Carbonization is a process of the formation of coal. As coal is formed by decaying vegetation under heat and pressure, the dead plants gradually turn into coal. This conversion of dead plants into coal is a process called carbonization. Peat is the inferior variety of coal. It contains a high amount of moisture and less than 40% of carbon.
