Question

Choose the correct statement from the following:
A) It is difficult to transport natural gas through pipes
B) The disadvantage of natural gas is that it cannot be used directly for burning in homes
C) Natural gas is stored under low pressure as compressed natural gas
D) Natural gas cannot be used for power generation

Answer 1

Hint: To choose the correct statement, you should have knowledge about the uses and transportation of natural gas. Remember that we use natural gas in our homes for cooking purposes. Also, natural gas is inflammable so due to safety concerns, its transportation is not that easy.

Complete answer:
Natural gas is a naturally occurring hydrocarbon gas mixture of combustible gases. It is formed underground by the decomposition of organic materials in plants and animals.
Uses of natural gas:
- It is used as a source of energy for heating, cooking and power generation.
- It is also used as a fuel for automobiles.
- It can be efficiently burned to generate heat and electricity.
Transportation of natural gas:
Sometimes, it is not easy to store and transport natural gas. The transport of natural gas is difficult through pipelines because the friction in the pipeline causes the gas to heat up. Thus, due to safety concerns, it is not transported through pipelines to long distances. Instead, gas is turned into liquid at a liquefaction plant and then transported as liquefied natural gas (LNG) for long distances. Natural gas as compressed natural gas (CNG) is transported at high pressure. Thus, it is correct to say that natural gas is stored under high pressure as compressed natural gas.
On summarising all the above points, you can conclude that only the statement given in option (A) is correct.

Thus, option A is the answer.

Additional information:
Natural gas is a non-renewable hydrocarbon gas. It is formed when layers of decomposing animals and plants organic matter are exposed to intense pressure and heat under the surface of earth over millions of years.

Note:
It should be noted that Liquefied natural gas (LNG) is the more preferred form for long distances and high volume transportation of natural gas, whereas pipelines is preferred for transport for small distances.
