Coal is fuel. Chemically similar to the more refined petroleum-derived kerosene it consists mainly of several hydrocarbons of the alkane series with 10 to 16 carbon atoms in each molecule with a boiling point of 175 C to 325 C 347 F to 617 F.

Originally from the sun but then probably from fossil fuels coal oil and natural gas which are burned to generate electricity.
What is coal originally derived from. In fact food dye is pulled off of the market regularly because of health concerns. Coal one of the most important primary fossil fuels a solid carbon-rich material usually brown or black that most often occurs in stratified sedimentary deposits which may later be subjected to high temperatures and pressures during mountain building resulting in. Coal is extracted from the ground and used to generate electricity.
Where does coal come from originally. Coal is a sedimentary rock which means it was formed through time. Start studying Geology 4.
Coal is classified into four main types or ranks. The unqualified term coke usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. Coal is a fossil fuel formed from vegetation which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams.
The conditions that would eventually create coal began to develop about 300 million years ago during the Carboniferous period. Most scientists think natural gas. Petroleum is a fossil fuel derived from ancient fossilized organic materials such as zooplankton and algae.
Anthracite bituminous lignite peat coke and charcoal are the various forms of coals. Because it originally formed from plants coal contains mostly carbon hydrogen oxygen and nitrogen. Coal is called a fossil fuel because it was made from plants that were once alive.
----- Plants using photosynthesis convert sunlight water and. Most scientists think natural gas. Origin of coal Plant matter.
Petroleum and natural gas are also fuels. Learn vocabulary terms and more with flashcards games and other study tools. Fossil fuel s are formed from the remains of ancient organisms.
The coal we use today took millions of years to form. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. Vast amounts of these remains settled to sea or lake bottoms where they were covered in stagnant water water with no dissolved oxygen or sediments such as mud and silt faster than they could decompose aerobically.
Coal is essentially fossilized carbon. Coal is from decayed plants buried hundreds of millions of years ago. The majority of todays coal deposits are found in sedimentary formations called peneplains or low dip foldings.
It can be burned to make heat or energy. It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm. New plants grew up to take their places and when these died still more grew.
Anthracite the highest coal rank material which appears to have been derived from algae is known. Although peat is used as a source. On the microscopic level coal is made up of organic particles called macerals.
If you are lucky the energy might be renewable from solar wind. These chemicals are in no way made to be ingested by humans or any other animal. Coal has a Volatile matter content whereas Coke has relatively very low Volatile matter content which suits it for a better fuel.
Petroleum and natural gas are also fuels. They are a derivative of Petrochemicals and Coal tar. Coal helped create the carbon-based branch of chemistry we call organic chemistry.
When coal is heated in the absence of air its complex mixture breaks down into simpler forms. Where did coal originally come from. However many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras.
The energy is coal was once sunlight energy that plants used. As the plants grew some died and fell into the swamp waters. Because coal takes millions of years to develop and there is a limited amount of it it is a nonrenewable resource.
It is formed from plant remains that have been compacted. Coal oil is a shale oil obtained from the destructive distillation of cannel coal mineral wax or bituminous shale once used widely for illumination. Vast deposits of coal originate in former wetlandscalled coal foreststhat covered much of the Earths tropical land areas during the late Carboniferous Pennsylvanian and Permian times.
Coal is fuel. Macerals are to coal as sediment grains and cements are to sedimentary rocks. Coal is black or brownish-black and has a composition that including inherent moisture consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.
Plants need sunlight to grow. Coal formed millions of years ago when the earth was covered with huge swampy forests where plants - giant ferns reeds and mosses - grew. It can be burned to make heat or energy.
A similar product called petroleum coke or pet coke is obtained from crude oil in oil refineries. Since coal comes from plants and plants get their energy from the sun the energy in coal also came from the sun. Coke may also be formed naturally by geologic processes.
The energy is coal was once sunlight energy that plants used. Macerals are the altered remains and byproducts of the original plant material from which the coal-forming peat originated. Coal is a natural occurring substance whereas Coke prepared material with few impurities and high Carbon content usually made from Coal.
Coal energy is energy derived from the burning of coal. Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible.
