Question

Name the varieties of coal having maximum and minimum carbon contents, respectively.

Answer 1

The variety of coal having maximum carbon contents:

Anthracite coal is the best quality coal with carbon content ranging from 80 to 95 percent. It is hard and contains very few impurities in the form of volatile matter and moisture. It ignites slowly thus releasing a large amount of energy on burning. It burns with a blue flame.

The variety of coal having minimum carbon contents:

Peat is light brown and contains only 50-60% carbon. It is the most inferior form of coal.
