Question

Due to which of the following property of gases, large volumes of CNG can be filled in small cylinders easily?

• A. Compressibility
• B. High density
• C. Fixed shape
• D. Inflammability

Answer 1

The correct option is A Compressibility

Due to the property of strong force of attraction between particles of a gas, a very large volume of the CNG can be fit or compressed into a small cylinder. In other words, the property of high compressibility plays an important role in the above mentioned phenomenon to fit large volumes of gases into a small cylinder.
Inflammability is the property of easily igniting, which isn't related to the given condition.
Fixed shape is not a property of gases and also gases have a very low density as compared to other states of matter.
