Description
Coal is a black sedimentary rock occurring in coal beds and coal mines. Coal is mined from these coal beds and mines. It takes millions of years for its formation. It occurs naturally. When plants and dead animals decay and get buried under the mud, carbon gets trapped in the sediments and carbonizations take places.
Coal has very few impurities in it known as coke and also has a high carbon content. It has a solid state of matter. Its components are the destructive distillation of low-ash, low-sulphur bituminous coal which derives from carbonaceous material and can be found in nature; usually a grey, porous and hard substance. It is also known as pet coke or petroleum coke.
