IPA: /ˈɡeɪziəsnəs/
KK: /ˈɡeɪʃəsnəs/
The state or quality of being in the form of gas.
The gaseousness of the atmosphere can change with temperature and pressure.
Gaseousness → It is formed from "gas" (from Latin *gas*, meaning vapor or air) and "-ous" (meaning full of) combined with the suffix "-ness" (meaning the state or quality of). The word "gaseousness" refers to the state or quality of being full of gas or vapor.
Think of 'gas' as a substance that is 'full of' something, and '-ness' indicates a state. This helps you remember that 'gaseousness' describes the quality of being in a gaseous state.
