Due to which of the following property of gases, large volumes of CNG can be filled in small cylinders easily?
Gas particles have a large spaces between their molecules. This implies that they have very low densities. They are compressible and large volumes of gases can be confined to the small space inside a small cylinder when pressurised.
Inflammability refers to the ease with which something catches fire.
Gases have no fixed shape; they occupy all the space provided to them.
