anthracite coal
# A burned or partly burned substance, such as coal, that is not reduced to ashes but is incapable of further combustion. # A partly charred substance that can burn further but without flame.
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.
It means the coal is good
Coal does not produce a visible flame because it needs a high amount of heat to ignite and burn. When coal is heated, it first releases volatile gases which can be lit to produce a flame. The coal itself then burns with a red glow due to the heat generated from the burning gases.

Use the blue inner flame when heating a piece of solid coal on a Bunsen burner. Adjust the air hole to control the intensity of the flame, ensuring efficient heating of the coal.
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.
Coal has potential chemical energy which is released as heat when it is burned.
Neither. Flame is a mixture of air and partially burned material.
When you burn coal.
Copper burns with a green flame when ignited with oxygen.
