What is the texture of coal?
The texture of coal is a 'hard, shiny, black rock. However, the 'hardness' and the 'shininess' can vary depending on the impurities present. However, it is always black. The texture of coal can vary from Peat, )A black wet earth) coal in its early stages of formation. (Burns/combusts with a lot of smoke) Then Lignite ; a soft black rock, with no wetness. ( burns/combusts with less smoke). Then coal as described above ( burns/combusts with a hot bright flame, dependent on the amount of oxygen draught present). Finally Anthracite ; hard and shiny ( Sometimes known as 'Black Diamond'( burns/combusts with a hot bright bluish flame, dependent on the amount of oxygen draught present).,
What are advantges of coal?
The advantage of coal is that it is easily mined. Other then that it runs out fast, it burns to C02, there is very little of it, takes really long time to produce and it is hard to convert to energy.
Why is coke preferred over coal for burning?
Coke, often made from bituminous coal refuse, is formed from burning off volatile components. That leaves solid fuel that burns longer and hotter than coal.Anthracite (hard) coal burns the hottest and cleanest, but this coal is in shorter supply because it takes longest to form.Bituminous (soft) coal has variable amounts of volatile components (low, medium, high) and burns 'dirty'. But it provides long, fairly even burning.Factories could and did use bituminous coal. But burning coal refuse to make coal rescued the coal while getting rid of gunk and impurities. Steel mills, which needed high, even, and longer-lasting burns for steel production, required coke.For coal companies, mining and processing of "coal and coke" increased revenues from all grades of coal. At one point, Fayette County and Washington County both in SW Pennsylvania were dotted with "beehive" coke ovens used to burn off coal's impurities.
How are bituminous coal and anthracite coal alike?
Bituminous coal is relatively soft and dull, as opposed to anthracite which is hard and shiny. Anthracite is also much more dense and pure. Because of its purity (can be up to 98% carbon), Anthracite burns a very hot, smokeless flame.

What type of coal was exposed to the highest temperature and pressure for the longest time?
Very hard coals such as anthracite were formed under these conditions.
Is lignite coal?
Yes, but very poor grade. Types of coal by grade:Anthracite - hard coal, almost pure carbon, burns very cleanBituminous - soft coal, contains bitumen a tar like material, burns smokyLignite - very soft coal, often contains unfossilized plant materialPeat - cut from peat bogs, must be dried first to remove waterBituminous coal is often "coked" by roasting in coking oven to make coke, which is of similar grade to natural Anthracite coal. The bitumen vapors driven off make an excellent illuminating gas or fuel for stationary internal combustion engines.
