Q. Consider the following pairs: | Coal | Well Known As |
| Anthracite | Hardest type of coal with the highest carbon content |
| Lignite | Brown coal with the lowest carbon content |
| Bituminous | Most abundant type of coal used for electricity generation |
How many of the above pairs are correctly matched?
Answer:
All three pairs
Notes: - Anthracite: It is indeed the hardest type of coal with the highest carbon content, making it highly efficient for burning.
- Lignite: This type of coal is characterized as brown coal and has the lowest carbon content, making it less efficient than other types.
- Bituminous: It is the most abundant type of coal and is primarily used for electricity generation due to its high carbon content and energy output.
Thus, all three pairs are correct.
