What is the residue from coal?
The residue from coal is known as coal ash or fly ash. It is a fine, powdery material that is generated when coal is burned in power plants. Coal ash can contain heavy metals and other toxic substances, posing environmental and health risks if not properly managed.
What does coal ash form into when burned?
When coal is burned, coal ash forms into a residue that contains various minerals, metals, and other impurities like silica, iron, aluminum, calcium, and magnesium. This residue is commonly known as coal ash or fly ash and is often collected and disposed of at coal-fired power plants.
What is a wood or coal partly burned but no longer flaming called?
That is called "charcoal." It is the residue left after partially burning wood or coal in a low-oxygen environment.
Why does a diamond turn into coal when it's burned?
When a diamond is burned, it does not turn into coal. Instead, it undergoes combustion and forms carbon dioxide gas, leaving behind a small amount of ash residue. Coal is a completely different substance that forms over millions of years from plant matter undergoing pressure and heat.
How much ash in one ton of antracite coal?
Approximately 10-15% of the weight of anthracite coal is comprised of ash. This means that in one ton of anthracite coal, you can expect to find around 200-300 pounds of ash. Ash is the residue left over after the coal is burned, consisting of minerals and non-combustible materials.

What are cinders made from?
A cinder is a burned or partly burned substance such as coal that is not reduced to ashes but is incapable of further combustion.

How would you describe the physical properties of coal?
Coal is a black, combustible sedimentary rock that is mainly composed of carbon. It is brittle, typically black or brown in color, and has a wide range of heating values depending on the type of coal. Coal can leave a powdery residue when handled and may have a distinct odor when burned.

Which coal is burned with the least flame?
anthracite coal
How is coal used in Washington?
it is burned
Is coal burned in a furnace?
Yes, coal can be burned in a furnace to generate heat or electricity. When coal is burned, it releases energy in the form of heat which can then be used for various purposes. However, burning coal releases harmful emissions into the atmosphere, contributing to air pollution and climate change.
What energy does coal have?
Coal has potential chemical energy which is released as heat when it is burned.
Why does coal smell so bad?
Coal contains sulfur compounds that produce a foul odor when burned. These sulfur compounds are released as sulfur dioxide when coal is burned, contributing to air pollution and causing the characteristic smell associated with coal combustion. Additionally, impurities in coal such as volatile organic compounds can also contribute to the unpleasant smell when coal is burned.
