Paper 5, Paper 6
Revise: Energy dissipation and efficiencyThermal insulation reduces unwanted energy transfer by heating. For example, loft insulation and cavity wall insulation reduce the rate at which energy leaves a warm building. Materials containing trapped air are useful because air is a poor thermal conductor.
A material or arrangement that reduces unwanted energy transfer between a system and its surroundings.
