All coal contains carbon. The carbon atoms in coal are bonded in an extensive network. It is this network of bonding which holds chemical potential energy. When these bonds are broken, heat is released, and this potential energy is turned into thermal energy.

What is coal energy?
Coal energy is energy derived from the burning of coal. Coal is essentially fossilized carbon.
How is the energy stored in coal?
In chemical bonds.
Why is diamond more dense than coal?
Because a diamond has more carbon bonds than coal. Carbon bonds are very strong and can only be broken in one direction. Diamonds have 3 carbon bonds, which makes it very hard. Diamonds can only be cut in one direction, that is because of the number of carbon bonds.
Which variety of coal contains the highest percentage of carbon?
Anthracite Coal
Which kind of coal contains the most carbon?
anthracite
When coal burns what type of energy is it?
The chemical energy stored in the coal is converted into heat energy for space heating or to drive an engine. Coal contains carbon that mostly came from the atmosphere via the process of photosynthesis by vegetation using the Sun's energy to break down carbon dioxide in the air into carbon and oxygen. When those chemical bonds are reformed in the burning process, that solar energy is released and carbon dioxide is re-formed.
Electricity from coal is called?
Coal is the largest source of energy for the generation of electricity contains mainly carbon, the conversion of dead vegetation into coal is called carbonization.

How is coal converted into other forms of energy?
Coal is normally burned to produce heat. This is done by burning the coal with oxygen from the atmosphere. The process unites carbon and oxygen to produce carbon dioxide and the formation of the chemical bonds in this process releases energy as heat. Burning one ton of coal creates about 3 tons of carbon dioxide. The additional mass comes from the oxygen taken from the atmosphere.

Is a burning match potential energy?
Burning coal has chemical potential energy, because the energy is stored up in the bonds between the carbon molecules, and when the coal is burned, the stored energy is released and transformed into heat, light, and even sometimes sound energy.
Is coal a form of Solar energy?
Yes, the energy stored in coal came from the sun. Plants using an ingenious process called photosynthesis, use energy from the sun, to take carbon-dioxide from the air, use the carbon and release the oxygen back to the air. After the plant is eaten or dies and is decomposed or burned (the net effect is the same) the oxygen again breaks the chemical bonds, releasing the energy from the sun and liberating the carbon-dioxide back to the air to become the next generation of plants. Coal is carbon from the air and energy from the sun.
Does coal produce energy?
Coal does not produce energy. Think of coal (or any current fuel source) as a storage medium similar to a battery, or even a mass at a height. The potential energy that can be released is finite, but available for use. All that is required are the proper conditions to do so. These conditions are: Sufficient Heat to provide the energy needed to break enough of the carbon and hydrogen bonds so that the process becomes self sustaining. Sufficent Oxygen so that the carbon and hydrogen bonds and creates molecules at alower energy level. So Where did the energy come from that is stored in the coal. Eventually it can be traced back to sunlight that was absorbed by plants and used to create carbon hydrogen molecules.
What type of rock contains most carbon?
Coal.
Which kind of coal contains the most carbon?
anthracite
