Question

Q. Arrange the following types of coal in decreasing order in terms of their carbon content

Select the correct answer using the codes given below:

• A. 2-3-4-1
• B. 2-4-3-1
• C. 1-4-3-2
• D. 1-4-2-3

Answer 1

The correct option is C 1-4-3-2

Explanation:

Anthracite:

• Anthracite is the best quality of coal which carries 80 to 95 percent carbon content. It ignites slowly with a blue flame.
• It has the highest calorific value.
• It is found in small quantities in Jammu and Kashmir.

Bituminous:

• Bituminous carries 60 to 80 percent of carbon content and a low level of moisture content.
• It is widely used and has a high calorific value.
• It is found in Jharkhand, West Bengal, Odisha, Chhattisgarh, and Madhya Pradesh.

Lignite:

• Lignite carries 40 to 55 percent carbon content and has high moisture content so it gives smoke when burnt.
• It is low-grade coal since its calorific value is low.
• It is found in Giral (Rajasthan), Lakhimpur (Assam), and Neyveli (Tamil Nadu).

Peat:

• Peat has less than 40 percent of carbon content.
• It is in the first stage of transformation from wood to coal. It has a low calorific value and burns like wood.
