Question

Which property of coke makes it useful in the manufacture of steel?

• A. It generates intense heat but little smoke
• B. It used as reducing agent
• C. Both A and B
• D. None of these

Answer 1

Answer: (C)

Both A and B

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel.
