Gas can be composed of single atoms (such as rare gases), single molecules composed of one element (such as oxygen), compound molecules composed of multiple elements (such as carbon dioxide), etc. Gas mixtures can include multiple gas substances, such as air. The significant difference between gas and liquid and solid is that there is a large gap between gas particles. This gap makes it difficult for the human eye to detect colorless gas. Gas is a fluid like liquid: it can flow and deform. Unlike liquid, gas can be compressed. If there is no restriction (container or force field), gas can diffuse, its volume is not limited, not fixed, and the atoms or molecules of gaseous substances can move freely with respect to each other.
