A historical physical name for a gas or vapour, emphasizing its mobility and appreciable compressibility. It does not imply an exactly ideal gas or prevent a vapour from undergoing condensation.
A relation among quantities such as pressure, volume, temperature and amount of substance for a gas.

Gas is one of the four fundamental states of matter, along with solid, liquid, and plasma. In a gaseous state, substances have particles that are widely spaced and move freely, which gives gases the ability to expand to fill the volume of their container. Some key characteristics of gases include: 1. **Indefinite Shape and Volume**: Gases do not have a fixed shape or volume. They take the shape and volume of their container.
