  1. 4. When a solid or a liqurd takes up space or takes up another substance space through pores and spaces in molecules.
  2. 5. Device that uses electricity to function.
  3. 7. A clear liqurd that is colourless and a type of liqurd.
  4. 8. Emission of light by a solid that has been heated until it glows
  5. 13. Ability to do work.
  6. 14. Eletric current does not flow freely.
  7. 18. The bouncing back of light from any shiny surface.
  8. 19. Capable of being stretched or expande transformation. When energy changes from one place to another.
  9. 23. energy- Energy created by heat and light from the sun
  10. 24. When a wave (example light) travels through medium.
  11. 25. Form of energy being released by nucleus.
  12. 27. The smallest part of a substance that cannot break down chemically.
  13. 28. Energy-Energy that is stored in an object due to its position, properties and forces acting on it.
Down
  1. 1. The process of heat energy that is basically with molecus and atoms.
  2. 2. Acoustics.
  3. 3. The flow of heat by movement by warm gases.
  4. 6. A device that stores chemical energy and converts to electric energy.
  5. 9. Changing from one substance tEfficiency ciency A measure of how near a process of being perfect.
  6. 10. A type of rock that's mainly composed to carbon.
  7. 11. Emit light by their own.
  8. 12. Tiny piece of matter.
  9. 15. Fuel A non renewable source that is basically combined with oil and coal.
  10. 16. energy- Sources that will never run Non-renewablewable energy- Energy that will run out.
  11. 17. The brightness you see.
  12. 20. energy relsed in form of particle waves.
  13. 21. Energy-Energy movement where anything moves it has kinetic energy. The faster the object moves more kinetic energy it has.
  14. 22. The rate of doing work.
  15. 26. An invisible force that pulls the object towards each other.
