Question

Coal is produced in the industry to get which of the following products?
A.Coke
B.Coal tar
C.Coal gas
D.All of these

Answer 1

We have to know that coal is obtained because of natural processes such as flooding; the forests went underneath the soil. As a high amount of soil is deposited over them, they become compressed. They sank deeper due to an increase in temperature. In high temperature, and high pressure, coal is obtained when dead plants are converted. We have to know coal is also known as fossil fuel.

Complete answer:
We have to know that when coal is heated in air, it burns and gaseous carbon dioxide is produced. We have to know that while processing coal, we get several useful products like coal gas, coal tar, and coke.
We have to know that coke is a porous, tough, and black substance which is an extremely pure form of carbon. We can use coke during the production of steel and also during the extraction of several metals. So, Option (A) is correct.
We have to know that coal tar is a thick liquid which is black in color and has an unpleasant odor. Coal tar is a combination of more than two hundred products. We can say that the products which are derived from coal tar are used as preparing materials for production of several substances that we use in daily life and in industry such as drugs, synthetic dyes, plastics, paints, photographic materials, roofing materials etc. We can say that naphthalene balls that we used to repel moths are derived from coal tar. Option (B) is correct.
We have to know that coal gas is derived at the time of manufacturing coal to produce coke. We can use coal gas as fuel in several industries found near the processing of coal plants.
Option (C) is correct.
Since all three options are correct, the best option is (D) all of these.

Option (D) is correct.

Note:
We have to know that coal is an exhaustible natural resource because the availability of coal in nature is limited and they could be exhausted by human activities. We can use coal as one of the fuels that we can use for cooking food. It was earlier used in engines to liberate steam to move the engine. We can also use coal in several industries as fuel.
