IPA: /nɒŋˈɡeɪʃəs/
KK: /nɒŋˈɡeɪʃəs/
Referring to a state of matter that is not in the form of gas, such as solid or liquid.
Water is a nongaseous substance at room temperature.
Nongaseous → It is formed from "non-" (meaning not) and "gaseous" (from Latin "gasium", meaning vapor or gas). The word "nongaseous" means not in a gaseous state or not consisting of gas.
Think of 'non-' meaning not, and 'gaseous' referring to gas — so nongaseous describes something that is not gas.
