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 vaporization and its forms, relay thermodynamics, enthalpy values and applications from physics and chemistry references, and distinguish vaporization from sublimation, condensation and the everyday sense of vaping.

The phase transition of a substance from liquid to gas, occurring either as evaporation from the surface at any temperature below the boiling point or as boiling throughout the liquid at the boiling point, requiring the enthalpy of vaporization to overcome intermolecular forces and cooling the remaining liquid; vaporization underlies distillation, refrigeration, steam power, weather and sweating, and its reverse is condensation.

What it is for: Not applicable; a physical process.

It can be explain evaporation and boiling; relay thermodynamics; describe applications; distinguish related processes.

Distinguishing features

Liquid to gas

Surface and bulk forms

Latent heat

Pressure dependence

What it looks like

Not a visible object; liquid turning to vapour.

Physical character

enthalpy of vaporization of water: 40.65 kJ/mol - at 100 C

boiling point of water: 100 C - at 1 atm

Clausius-Clapeyron relation: links vapour pressure and temperature law

How it is recognised

Liquid to gas phase change

Evaporation, boiling, flash vaporization

Sublimation goes from solid to gas; condensation is the reverse; vaping is inhaling aerosol
