  1. 2. Energy resources that are NOT replaced/replenished as easily as they are used.
  2. 3. ______ is measured in kg and tells us how much matter is in a material.
  3. 8. A variable in practicals - the thing you change.
  4. 10. The energy required to change 1 kg of material by 1 degree celcius. It is a property of the material.
  5. 12. Energy resources that are replaced/replenished as easily as they are used.
  6. 15. A variable in practicals - the thing you measure.
  7. 16. _______ = useful energy out/total energy in
  8. 17. Energy store - examples are anything that moves.
