solid
Let an agent explain the solid state and its properties, distinguish crystalline and amorphous solids and classes of solid materials, describe phase changes and applications, 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 the solid state and its properties, distinguish crystalline and amorphous solids and classes of solid materials, describe phase changes and applications, and support learning.
One of the fundamental states of matter, in which particles are closely packed and held in fixed positions by strong interactions so that the material keeps a definite shape and volume and resists deformation, existing as crystalline solids with ordered lattices or amorphous solids without long-range order; solids include metals, ceramics, polymers, minerals and solid foods, and are studied in solid state physics, chemistry, materials science and engineering.
What it is for: The solid state of matter.
It can be explain the solid state; distinguish kinds of solids; describe phase changes and applications; support learning.
