Which statement correctly describes the gaseous state of matter?

1. Gases differ from solids and liquids mainly in how far apart their particles sit. 2. In a gas the inter-particle distance is large, which is why gases are easily compressed. 3. Particles vibrating about fixed positions describes a solid, where they cannot move past one another. 4. Closely packed particles describe solids and liquids, not gases. 5. A gas has neither definite shape nor definite volume, since it always fills the whole container — the 'indefinite shape, definite volume' option describes a liquid. _Source: NECTA CSEE 2022 Physics 031, Question 1: Multiple Choice, item (iii)_
