Conservation, dissipation and national and global energy sources
Child standards (6)
- UK-GCSE-SCIENCE-PHYS-ENG-02-01describe with examples where there are energy transfers in a system, that there is no net change to the total energy of a closed system (qualitative only)
- UK-GCSE-SCIENCE-PHYS-ENG-02-02describe, with examples, how in all system changes, energy is dissipated, so that it is stored in less useful ways
- UK-GCSE-SCIENCE-PHYS-ENG-02-03explain ways of reducing unwanted energy transfer e.g. through lubrication, thermal insulation; describe the effects, on the rate of cooling of a building, of thickness and thermal conductivity of its walls (qualitative only)
- UK-GCSE-SCIENCE-PHYS-ENG-02-04calculate energy efficiency for any energy transfer, and describe ways to increase efficiency
- UK-GCSE-SCIENCE-PHYS-ENG-02-05describe the main energy sources available for use on Earth (including fossil fuels, nuclear fuel, bio-fuel, wind, hydro-electricity, the tides and the Sun), compare the ways in which they are used and distinguish between renewable and non-renewable sources
- UK-GCSE-SCIENCE-PHYS-ENG-02-06explain patterns and trends in the use of energy resources
