Question

Which statement is correct about natural gas?

A) It is used in the manufacture of steel.

B) It is used in railway engines to produce steam.

C) Both of the above statements are correct.

D) None of the above statements is correct.

Answer 1

The correct answer is A) It is used in the manufacture of steel. Natural gas is a significant heat source in industrial processes and contributes to electricity production but is not traditionally used in railway engines to produce steam.

Step-by-step explanation:

The correct statement about natural gas is that it is used in the manufacture of steel. Natural gas is often utilized as a heat source in industrial processes, including the direct heating of furnaces and ovens required in the steel-making process. Therefore, option A is the correct answer.

Natural gas is also a significant contributor to electricity production through its use in gas turbine power plants. It is preferred over coal for electricity generation in many cases because it produces less CO₂ per unit of energy consumed. However, railway engines traditionally use diesel or electricity rather than natural gas to produce steam or power the engines.
