Mastery checklist

Know what success looks like.

  1. 01

    Define the system and distinguish temperature, internal energy, and transferred energy.

  2. 02

    Connect the macroscopic process to a particle or molecular explanation.

  3. 03

    Use an energy balance with consistent signs, units, and process assumptions.

Exam lens

Build, apply, check.

9 Thermodynamics is identified as 15–18% in this curriculum map. Build the concept first, then practise selecting a model, showing working, and checking the final result.
