Answer 2

Anthracite, bituminous, sub-bituminous, and lignite coal are the four basic forms of coal. The amount and kind of carbon present in the coal, as well as its capacity to produce heat when burned, are used to rank the coal.

Explanation:

• Anthracite: Because it contains between 86 and 97 percent carbon, it has the highest heating value of all the coal varieties.
• Bituminous coal has a carbon content ranging from 45 to 86 percent. It is the most common form of coal found in the United States, accounting for around 44% of total coal output in the United States in 2020.
• Sub-bituminous coal has a lower heating value than bituminous coal and has a carbon content of 35 to 45 percent. Lignite coal has a carbon content of 25 to 35 percent and has the lowest energy content of all the coal types known.
• Lignite also has a high moisture content, which contributes to its low heating value.
