evaporation
Let an agent explain evaporation and the factors controlling it, compute evaporation in practical contexts, explain its role in climate and industry, and separate cooking senses.
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 evaporation and the factors controlling it, compute evaporation in practical contexts, explain its role in climate and industry, and separate cooking senses.
The change of a liquid into vapour from its surface at temperatures below boiling, driven by molecular energy and affected by temperature, humidity, airflow and surface area, occurring in nature as part of the water cycle and used in cooling, drying, concentration and cooking techniques such as steaming; flash evaporation is rapid vaporisation on sudden pressure drop.
What it is for: Physics, climate, industry and everyday life.
It can be explain evaporation and its controls; estimate evaporation rates; explain roles in the water cycle and cooling; describe industrial and culinary uses.
Distinguishing features
Surface vaporisation
Below boiling point
Cooling effect
Environment-dependent rate
What it looks like
Liquid disappearing into vapour, sometimes with visible mist.
How it is recognised
Vapour from a liquid surface below boiling
Faster with heat, wind and dryness
Boiling occurs throughout the liquid at boiling point
