Answer:

heya here is ur answer mark as brainliest

Explanation:

Coal is ranked in six different categories:

1. Peat - not really a coal; it is undeveloped, soft and spongy. It is 20-25% carbon, and was deposited during the last 100 years by decomposed plant remains.    

2. Lignite- the first "real" coal.  It has a low heating value and is often found near the earth's surface. Lignite coal loses its moisture when exposed to air.

3. Subbituminous - lower in carbon content than bituminous coal.  It also loses its moisture when exposed to air.  When exposed to wetness it

4. Bituminous - has a high carbon content (65-85%), and a low oxygen content (5-15%).  It usually burns with a yellow flame.

5. Semianthracite - a hard coal but softer than anthracite.  It has a fixed carbon percentage of 80-85%.  It contains more volatile matter than anthracite and also burns more freely.

6. Anthracite - hard, durable, high density.  It has low volatile matter and is 85-98% fixed carbon.  It ignites slowly and burns with little flame or smoke
