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 ...

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.

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.

The slow process of conservation of dead vegetation into coal is called Carbonisation. Since it was formed from the remain of vegetation, coal is also called a fossil fuel. When heated in air, coal burns and produces mainly carbon dioxide gas. Coal is processed in industry to get some useful products such as coke, coal tar, coal gas.

The Process of conversion of wood into coal by biochemical process is known as Carbonization. Coal burns cleaner than wood burning coal was easier because coal burned longer than wood. Carbonization is the term for the conversion of an organic substance into carbon or a carboncontaining residue through pyrolysis or destructive distillation.

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.

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]

Step 3. If you know the potential energies for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is. [KE_i + PE_i = KE_f + PE_f.] Step 4.

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 is the most abundantly found fossil fuel and is used as a domestic fuel, in industries such as iron and steel, steam engines and to generate electricity. Electricity from coal is called thermal power. The coal which we are using today was formed millions of years ago when giant ferns and swamps got buried under the layers of earth.

Coal and Petroleum. Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.

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.

Discuss Coal is a darkshaded rocklike fuel in which the substance of carbon can fluctuate somewhere in the range of 70 and 90%. It is framed by the deterioration of vegetation under intensity and strain. The course of coal arrangement is called carbonization, and the time span during which this cycle happens is known as the carboniferous age.
