gas
Let an agent handle gases by state-of-matter physics, common gases, safety (leaks, asphyxiation, pressure) and regulation, without providing harmful uses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle gases by state-of-matter physics, common gases, safety (leaks, asphyxiation, pressure) and regulation, without providing harmful uses.
One of the fundamental states of matter, in which particles move freely and fill any container, with no fixed shape or volume; also everyday gases such as natural gas, industrial gases and packaging gases.
What it is for: Physics and chemistry, fuel, industry, medicine and food packaging.
It can be explain gas behaviour and gas laws; identify common gases and hazards; respond safely to gas leaks; store gas cylinders safely.
Distinguishing features
No fixed shape or volume
Compressible
Described by gas laws
Some are flammable, toxic or asphyxiant
What it looks like
Usually invisible; sometimes coloured or detected by added odorants.
