Gases have least intermolecular forces between them and hence the gas molecules tend to stay apart as much as possible. Therefore, they occupy the whole volume in which they are kept.
Hope it helps.

There is little attraction between particles of gas. Thus, gas particles move freely in all directions. Therefore, gas completely fills the vessel in which it is kept.
