How it's used
Scientific and technical contexts are where this term primarily lives, as it is a direct translation of the state of matter. In casual daily life, people rarely use this word unless they are specifically discussing chemistry, physics, or safety hazards like gas leaks. For household gas, speakers almost always prefer specific terms like 煤氣 or 石油氣.

Common mistake
Avoid using this to refer to flatulence, as that is specifically called 屁 in Cantonese. Using 氣體 to describe bodily gas will sound overly clinical and unnatural.
