heat
Let an agent explain heat as energy transfer and its thermodynamic meaning, describe forms and mechanisms of heat transfer, support calculations and engineering questions, and address common misconceptions in teaching.
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 heat as energy transfer and its thermodynamic meaning, describe forms and mechanisms of heat transfer, support calculations and engineering questions, and address common misconceptions in teaching.
Energy transferred between systems or bodies because of a temperature difference, measured in joules, distinguished in thermodynamics from work and from internal energy, and appearing as sensible heat that changes temperature, latent heat absorbed or released in phase transitions, decay heat from radioactive materials, waste heat from engines and industry, and geothermal heat from the Earth; heat transfer by conduction, convection and radiation governs engineering, climate and everyday life.
What it is for: Energy transferred by temperature difference.
It can be explain the thermodynamic concept; describe forms and transfer mechanisms; support calculations; address misconceptions.
Distinguishing features
Process quantity
Joule units
Three transfer mechanisms
Latent and sensible forms
What it looks like
Not physical; energy in transfer.
How it is recognised
Energy transfer due to temperature difference
Sensible, latent, decay, waste, geothermal
Temperature is a state; internal energy is stored; work is transfer by force
