gaseousness
Quality of vapor
Gaseousness is the quality of being gaseous—existing in or having the properties of a gas rather than liquid or solid.
The term appears in scientific contexts describing physical states: The gaseousness of the sample increased as temperature rose.
Figuratively, it can suggest something insubstantial or bloated with empty content.
