Answer 1

Answer:

The correct answer is Option 2

Explanation:

• Coal is a very important fossil fuel. It is being used for thousands of years for generating electricity, running trains and by industries. It is also used for making many important products like coke, coal t, ar, and coal gas. These by-products are also beneficial for us too. Coke is produced slowly in a coke oven.
• Powdered coal is heated in the oven. If 1 tonne ( 1000 kg) of coal is heated it gives, 70% solid coke and 30 % coal tar and coal gas.
• Coke is effective scientifically as it produces double the heat content of the coal required to create. It is mostly used in a blast furnace to make steel.
• Coal tar is a thick that liquid which is used in soaps, ointments and
• shampoos. It has antifungal, anti itching, anti-inflammatory, and ant parasitic properties. It was a component of the first sealed roads.
• Coal gas is used as lightning fuel and some industries use it as fuels that are close to coal processing plants.
