Let an agent explain air, relay composition, uses, air quality and safety from atmospheric science and health sources, describe the named forms, route air quality and breathing-gas safety, and distinguish air from pure oxygen, the atmosphere as a whole, wind and breathing gas mixtures.

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 explain air, relay composition, uses, air quality and safety from atmospheric science and health sources, describe the named forms, route air quality and breathing-gas safety, and distinguish air from pure oxygen, the atmosphere as a whole, wind and breathing gas mixtures.

The mixture of gases forming Earth s atmosphere, mainly nitrogen and oxygen with argon, carbon dioxide, water vapour and trace gases, essential for respiration, combustion and weather, with forms the registry aliases name such as compressed air used in tools and diving, liquid air, breathing air standards, sea and fresh air as informal terms, and the meteorological air mass; air quality varies, and pollution from particulates and gases harms health, so people should follow air quality alerts, and compressed and breathing air for diving must meet purity standards to avoid poisoning.

What it is for: Respiration, combustion, weather and industrial uses.

It can be explain composition; relay uses; relay air quality and safety; distinguish related concepts.

Distinguishing features

Gas mixture

Mostly nitrogen and oxygen

Supports life and fire

Quality varies

What it looks like

Normally invisible; seen through haze, mist or pollution and felt as wind.

Physical character

nitrogen: about 78 percent - by volume

oxygen: about 21 percent - by volume

registry parents: gas, mixture note

How it is recognised

Mixture of atmospheric gases

Breathing air, compressed air, sea air, air mass, liquid air, fresh air

Pure oxygen is one gas; the atmosphere is the whole envelope; wind is moving air; breathing gas mixtures are engineered for diving

  • Should air masses be moved to meteorology entries?
