What are the physical and chemical methods used to refine coal?
Coal refinement involves both physical and chemical methods to improve its quality. Physically, techniques such as crushing, screening, and washing are used to separate impurities like dirt and ash from the coal. Chemically, processes such as coal gasification and liquefaction convert coal into cleaner fuels and chemicals, removing sulfur and other pollutants in the process. These methods enhance the efficiency and environmental performance of coal as an energy source.
Which methods are used to deliver chemical agents?
Theater Ballistic Missiles (TBM)
How is coal extracted from the earth?
Coal is extracted from the earth through a process called mining. This involves digging deep underground or using surface mining methods to access coal deposits. Machinery and tools are used to extract the coal, which is then transported to processing plants for further refinement.
What methods are used to deliver chemical agents?

How much does it cost to refine coal?
Coal does not get refined. Oil gets refined, but coal gets used as it is when it comes out of the coal mine. There is a process called coal gassification by which natural gas can be made from coal, but that is not really a form of refining, and in any event, most coal is simply burned, it is not gassified.
What methods are used in coal mining?
You need big buff legs to mine coal
Why is petroleum or coal not used more often?
Petroleum and coal are largely used in chemical industry or as fuels.
What are two methods used for mining coal?
it comes from lava
What energy does coal have?
Coal has potential chemical energy which is released as heat when it is burned.
What types of energy are in coal?
The main types of energy in coal are chemical energy, which is released when coal is burned, and potential energy stored within the coal itself. When coal is burned, the chemical energy is converted into thermal energy, which can be used for generating electricity or heating.
What are the methods used to predict products of chemical reactions?
The methods used to predict products of chemical reactions include understanding reaction types, balancing chemical equations, and applying knowledge of chemical properties and reactivity.
What are the two methods used for mining coal?
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
How is energy stored in coal?
Coal stores energy in the form of chemical energy that was originally produced by ancient plants through photosynthesis and then stored in the coal over millions of years. When coal is burned, the chemical energy is released as heat energy, which is then transformed into electricity or used for other purposes.
What are the two methods that people use to extract coal?
Open cast and mining are the 2 used
Does coal release chemical energy when used?
Yes, when it is burned (oxidized in air), it releases the chemical energy stored within its chemical bonds.
