What are the uses of coal class 10th?

Coal is an important natural resource widely used as a fuel and raw material in many industries. It helps generate electricity, provides heat, and serves as a base for several industrial products like coke, coal tar, and coal gas.

Energy Source

1. Electricity Generation: Coal is burned in thermal power plants to produce steam. This steam spins turbines, which generate electricity.

2. Industrial Fuel: Coal serves as a major fuel in industries such as cement, chemical, and steel manufacturing, where high heat is required.

3. Domestic Fuel: In some areas, coal is used in homes for cooking and heating, especially where other energy sources are limited.

4. Transportation (Historical): In the past, coal was used to power steam engines in railways and ships.

Raw Material for Other Products

1. Coke: Coke is a high-carbon substance made by heating coal in the absence of air. It is mainly used in blast furnaces for producing iron and steel.

2. Coal Tar: A thick, black liquid obtained from coal. It is used to make paints, synthetic dyes, medicines, and explosives.

3. Coal Gas: A gaseous fuel derived from coal, once commonly used for lighting and heating.

4. Chemicals: Coal is also used to produce several important chemicals, including benzole, sulphate of ammonia, and creosote, which have various industrial and agricultural applications.
