Solution

The molecules in the gaseous state are packed extremely loosely in comparison to solids and liquids.
Also between the molecules the force of attraction is very weak.
Due to this, the gaseous particles keep on moving in different directions as the molecules cannot stay held together.
As a result the gaseous molecules do not possess any definite shape or volume.
That is why, when gas is kept in a vessel of any shape or size, they fill up the vessel or container entirely.
Therefore, due to the very loosely packed molecules, the gases do not have any particular volume or shape hence, gasses completely fill the vessel in which they are kept.
