Why do gases have fluidity

We regard liquid and gases as fluid because they they have very less or almost negligible force of attraction and very large intermolecular spaces and hence they can flow in any direction. Same is the reason of its fluid nature.

Gases are considered to have fluidity as the particles of molecules in gases are loosely packed and hence have the ability to flow or move freely with ease. The substances that have the ability to flow is considered to have fluidity.
