उत्तर
Any matter that is a gas has no definite volume and no definite shape. The molecules in a gas are least closely packed and intermolecular space between them is very large when compared to solids and liquids. The intermolecular force of attraction between the particles are negligible. As a result, a liquid does not easily change its shape nor they have fixed volume.
