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 handle temperature by scale, measurement, conversion and safety, and route body temperature concerns to health guidance without diagnosis.

A physical quantity expressing how hot or cold something is, related to the average kinetic energy of particles, measured in kelvins (SI), degrees Celsius or degrees Fahrenheit; includes air, water and body temperature.

What it is for: Weather, cooking, science, industry and health.

It can be convert between temperature scales; choose and calibrate thermometers; follow food safety temperatures; recognise heat and cold emergencies.

Distinguishing features

Physical character

absolute zero: 0 K - -273.15 degC

water boiling at 1 atm: 100 degC

How it is recognised

Units K, degC, degF

Thermometers and sensors

Heat is energy transfer, not temperature

  1. Is the user asking to interpret their own symptoms? boundary
  2. How should they be referred to a clinician? action

What the second pass must settle

  • Should kinds of temperature be separate entries?
  • How should conversion be linked?
  • How should body temperature be split off?
