Question

Large volumes of C.N.G is available in small cylinders due to its property of ______.
A. High density
B. Low density
C. High compressibility
D. Easy availability

Answer 1

We know that C.N.G is compressed natural gas and it is used in place of gasoline, diesel and LPG. C.N.G is a natural gas which is made by compressing methane gas to less than 1% of its original volume.

Complete answer:
- We know that C.N.G is compressed natural gas and it is used in place of gasoline, diesel and LPG. C.N.G is a natural gas which is made by compressing methane gas to less than 1% of its original volume. Compressed natural gas mostly contains methane gas.
- Compressed natural gas is an eco-friendly replacement to gasoline. Compressed natural gas is much safer than gasoline and diesel. This is because it is not toxic and it does not contaminate or pollute groundwater.
- Compressed natural gas keeps pressure and stays clear. It is odourless and non-corrosive in nature. It can be used as a cost effective and greener replacement to petrol and diesel.
- The name C.N.G itself suggests that it is a compressed natural gas. The ‘compressed’ in the name suggests that the compressibility of the gas is high.
- As the gas is highly compressible, large volumes of C.N.G can be made available in small cylinders.
Thus, large volumes of C.N.G are available in small cylinders due to its property of high compressibility.

**Thus, the correct option is (C) high compressibility.

Note:** The major source of compressed natural gas is methane. Methane is the cleanest and nicest burning fuel. Compressed natural gas can generate engine power on mixing with air.
