P1b Keeping Homes Warm

You need to be able to:
  • Explain heat energy transfer by conduction, convection and radiation (linked to home and appliance design and including absorption and emission of IR)
  • Explain why heat conservation methods work, and evaluate different methods (air as an insulator, maximising heat energy to inside, minimising heat energy transfer to atmosphere, payback time)
  • Use the fact that energy is conserved in energy efficiency calculations
  1. How surfaces affect absorption and emission of. IR
