Bituminous coal is one of the most commonly used types of coal in the world due to its high energy content and relatively low cost. However, not all bituminous coal is the same. Some bituminous coals have a high degree of caking, while others are non-caking. In this question, we are asked to determine the carbon content of non-caking bituminous coal.

Explanation:

Caking vs. Non-Caking Bituminous Coal:

Caking coal is a type of bituminous coal that has a high degree of plasticity, which means it can be molded or shaped when it is heated. This property is due to the presence of certain chemical compounds in the coal, such as hydrocarbons and oxygen-containing functional groups. When caking coal is heated, these compounds break down and release gases that cause the coal to soften and become sticky or "plastic." This property is useful in the production of coke, which is a fuel used in steelmaking.

Non-caking coal, on the other hand, does not have this plasticity and does not soften or become sticky when heated. This type of coal is often used as a fuel for power generation and other industrial applications.

Carbon Content of Non-Caking Bituminous Coal:

The carbon content of coal is an important factor in determining its properties and suitability for various uses. Generally, the higher the carbon content, the higher the energy content of the coal. Non-caking bituminous coal typically has a carbon content of around 78-81%, which is lower than the carbon content of anthracite coal (which can have a carbon content of up to 95%).

Conclusion:

In conclusion, the correct answer to this question is option 'A' (78-81%). This range of carbon content is typical for non-caking bituminous coal, which does not have the plasticity and caking properties of other types of bituminous coal. Understanding the properties and characteristics of different types of coal is important for selecting the right fuel for a particular application.
