CONCEPTS: Definitions and units for heat capacity, specific heat capacity, latent heat, specific latent heat Latent heat Heat transfer (conduction, convection and radiation)
MANDATORY EXPERIMENTS: 9. Measurement of the specific heat capacity, e.g. of water or a metal by a mechanical or electrical method
10.Measurement of the specific latent heat of fusion of ice 11.Measurement of the specific latent heat of vaporisation of water
ACTIVITIES: Demonstration of conduction, convection and radiation
SCIENCE,TECHNOLOGY AND SOCIETY: Storage heaters (heat capacity) Heat pump, perspiration (latent heat) Conduction (U-valves: use in domestic situation) Convection (domestic hot-water and heating systems) Radiation (everyday examples such as solar heating)
