Whilch of these forms of coal contains the highest amount of carbon?

Options

A. Peat
B. Lignite
C. Anthracite
D. Bituminous coal

Answer

To determine which form of coal contains the highest amount of carbon, we can analyze the carbon content of each type of coal. The four main types of coal are peat, lignite, bituminous, and anthracite. Let's break down the carbon content for each type:

1. **Peat**: This is the earliest stage of coal formation and contains less than 60% carbon.

2. **Lignite**: This is a type of brown coal that contains approximately 65-70% carbon.

3. **Bituminous**: This type of coal is more mature than lignite and contains about 70-86% carbon.

4. **Anthracite**: This is the highest grade of coal and contains the most carbon, ranging from 86-92%.

Now, let's summarize the carbon content of each type of coal:
- Peat: < 60% carbon
- Lignite: 65-70% carbon
- Bituminous: 70-86% carbon
- Anthracite: 86-92% carbon

From this analysis, we can conclude that anthracite contains the highest amount of carbon among the four types of coal.

**Final Answer**: Anthracite contains the highest amount of carbon.
