Question

What is coal write its uses?

Answer 1

Coal is a combustible sedimentary rock composed mostly of carbon and hydrocarbons. The energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Over time, layers of dead plants at the bottom of the swamps were covered by layers of water and dirt, trapping the energy of the dead plants. The heat and pressure from the top layers turned the plant remains into coal. USES:- 1.It is used as energy resource. 2.Bituminous coal is also used to produce coke for making steel.

Answer 2

Answer:

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams 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. The coal industry has two principal markets, namely thermal coal (for energy use, including power generation and other applications such as the cement manufacturing sector), and metallurgical coal (principally for steel making); but there are also other coal uses, including conversion into gas or other energy or ...
