With reference to Natural Gas, consider the following statements: 1. It is stored under high pressure as Compressed Natural Gas (CNG). 2. It cannot be used directly for burning in homes through pipes. 3. It is used as a starting material for the manufacture of chemicals and fertilisers. Which of the statements given above is/are correct?

Correct Option The correct option is (c) 1 and 3 only. Explanation Natural gas is a fossil fuel primarily composed of methane ($CH_4$). It is a vital energy resource used for heating, cooking, electricity generation, and as a raw material in various industrial processes. Its versatility allows it to be transported via pipelines or stored under pressure. Statement-wise Analysis - Statement 1 is Correct: Natural gas is stored under high pressure as Compressed Natural Gas (CNG). Compressing the gas reduces its volume significantly, making it suitable for storage in cylinders and use as a cleaner fuel for transport vehicles. - Statement 2 is Incorrect: Natural gas can be used directly for burning in homes and factories. It is supplied through a network of pipelines, commonly referred to as Piped Natural Gas (PNG), which delivers fuel directly to household stoves and industrial burners without the need for storage cylinders. - Statement 3 is Correct: Natural gas is used as a starting material (feedstock) for the manufacture of a wide range of chemicals and fertilizers. For instance, it is a primary source of hydrogen used in the production of ammonia ($NH_3$) for urea and other nitrogenous fertilizers. Key Takeaway: Natural gas is a versatile hydrocarbon used as CNG for transport, PNG for domestic fuel, and as an industrial feedstock for producing fertilizers and chemicals.

Solution

Correct Option

The correct option is (c) 1 and 3 only.

Explanation

Natural gas is a fossil fuel primarily composed of methane ($CH_4$). It is a vital energy resource used for heating, cooking, electricity generation, and as a raw material in various industrial processes. Its versatility allows it to be transported via pipelines or stored under pressure.

Statement-wise Analysis

Statement 1 is Correct: Natural gas is stored under high pressure as Compressed Natural Gas (CNG). Compressing the gas reduces its volume significantly, making it suitable for storage in cylinders and use as a cleaner fuel for transport vehicles.
Statement 2 is Incorrect: Natural gas can be used directly for burning in homes and factories. It is supplied through a network of pipelines, commonly referred to as Piped Natural Gas (PNG), which delivers fuel directly to household stoves and industrial burners without the need for storage cylinders.
Statement 3 is Correct: Natural gas is used as a starting material (feedstock) for the manufacture of a wide range of chemicals and fertilizers. For instance, it is a primary source of hydrogen used in the production of ammonia ($NH_3$) for urea and other nitrogenous fertilizers.

Key Takeaway: Natural gas is a versatile hydrocarbon used as CNG for transport, PNG for domestic fuel, and as an industrial feedstock for producing fertilizers and chemicals.
