Across
  1. 1. A state of matter where particles are arranged in order close together, vibrating on the spot.
  2. 3. ______ is measured in kg and tells us how much matter is in a material.
  3. 6. _____ = mass/volume We can measure this using scales and a eureka can.
  4. 7. Energy store - examples are batteries, food and fuels.
  5. 12. Change of state from Liquid to Gas.
  6. 13. A variable in practicals - the thing you keep the same.
  7. 14. A state of matter where particles are far apart, moving freely and randomly.
  8. 16. Energy store - examples are anything that moves.
  9. 17. A variable in practicals - the thing you change.
  10. 18. By adding or removing heat we can change the _________ of a material.
  11. 22. Energy resources that are NOT replaced/replenished as easily as they are used.
Down
  1. 2. A variable in practicals - the thing you measure.
  2. 3. Change of state from Solid to Liquid.
  3. 4. The energy required to change 1 kg of material by 1 degree celcius. It is a property of the material.
  4. 5. Change of state from Liquid to Solid.
  5. 8. Change of state from Gas to Liquid.
  6. 9. Energy store - examples are anything that has heat.
  7. 10. _______ = useful energy out/total energy in
  8. 11. Energy Resource - oil, coal and gas.
  9. 15. A state of matter where particles are disordered and close together, allowed to slide past each other.
  10. 19. ______ is measured in Joules
  11. 20. The energy required to change the state of 1 kg of material at a constant temperature. It is a property of the material.
  12. 21. Energy resources that are replaced/replenished as easily as they are used.
