4.1.2.1 Energy transfers in a system
Paper 1 · Triple only
Spec reference: 4.1.2.1 Required practical 2 (physics only).
Triple-only content in this dot
- Investigate effectiveness of different insulating materials.
- Evaluate factors affecting insulation (thickness, conductivity, control variables, fair test quality).
- Link results to reducing unwanted thermal energy transfer.
Exam quick-check
- Can I explain method reliability/validity and suggest improvements?
- Can I connect observations to conduction/insulation ideas clearly?
