phase
Let an agent explain phases of matter and phase transitions, describe specialised phases in materials and condensed matter, separate this sense from temporal and wave phases, and support learning.
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 phases of matter and phase transitions, describe specialised phases in materials and condensed matter, separate this sense from temporal and wave phases, and support learning.
A region of a physical system with uniform physical and chemical properties, such as solid, liquid, gas and plasma, and finer distinctions such as crystalline polymorphs, magnetic domains, liquid crystal mesophases, hexatic phases and quantum phases, separated from other phases by boundaries and transformed through phase transitions; the term is also used for dispersed phases in colloids and, in geology, for tectonic phases, and is distinct from phase as a stage in time or in wave oscillation.
What it is for: Uniform regions of a physical system.
It can be explain phases and transitions; describe specialised phases; separate other senses; support learning.
Distinguishing features
Uniformity

Thermodynamic description
What it looks like
Not physical as a concept; seen as distinct states of matter.
How it is recognised
Uniform physical and chemical properties
Solid, liquid, gas, plasma and more
Phase in time is a stage; phase in waves is an angle
