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 plasma as a state of matter and its properties, describe natural and technological plasmas, support learning in plasma physics, and separate the blood plasma sense.

A state of matter consisting of a gas of ions and free electrons that is electrically conductive and responds collectively to electromagnetic fields, found in stars, the solar wind, the intracluster medium and other astrophysical settings, in lightning and auroras, and in laboratory and industrial devices such as fusion experiments, plasma displays and etching tools; plasma is often called the fourth state of matter, and the word also names the liquid component of blood, a separate sense.

What it is for: Ionised matter.

It can be explain properties; describe natural and technological plasmas; support learning; separate other senses.

Distinguishing features

Ionisation

Conductivity

Collective behaviour

Most common visible matter in the universe

What it looks like

Glowing ionised gas in stars, lightning, auroras and lamps.

How it is recognised

Ionised, conductive gas

Collective electromagnetic behaviour

Blood plasma is a liquid, another sense
