gases
Helium, oxygen, and methane
Gases is the plural of gas—substances like air, helium, or methane that expand to fill any container.
The word covers both natural phenomena (greenhouse gases) and practical applications (anesthetic gases).
In informal use, gases can mean instances of flatulence.
The verb form gases means supplies with gas or, informally, talks idly: He gases on about nothing.
