Across
  1. 2. is determined by the average atomic mass.
  2. 3. a kind of matter that cannot be separated into other kinds of matter by and physical means.
  3. 9. an atom or molecule that has a net charge do to losing or gaining an electron(s).
  4. 10. the process in which a solid turns directly into a gas
  5. 12. a miniature semiconductor that regulates or controls current or voltage flow.
  6. 16. the transfer of heat energy through space (not only outerspace)
  7. 17. this states that the sun is the center of our solar system and the planets revolve around it.
  8. 20. a surface or a line that is curved inward.
  9. 22. energy stored as a result of applying a force to deform an elastic object, E.X. coiling a spring
  10. 23. anything that takes up space.
  11. 24. forms when an atom completely transfers an electron(s).
  12. 27. creation of an EMF by moving a magnetic field around an electric conductor.
  13. 28. a semiconductor device that acts as a one-way switch for current.
  14. 29. 299,793,458 m/s.
  15. 30. objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks."
  16. 31. the scientific theory that matter is composed of particles called atoms
Down
  1. 1. states that mass is can neither be created nor destroyed, only change from state to state.
  2. 4. this wave can cause skin cancer and other skin problems, and is used kill bacteria and create florescent lights
  3. 5. hot air rises and cold air sinks
  4. 6. forms when two or more atoms share electrons,
  5. 7. liquid changing to the gas phase via boiling
  6. 8. mass of a unit volume of a material substance. The formula to find this is Mass/Volume.
  7. 11. the potential energy an object has in relation to another object due to gravity
  8. 13. the rate of flow of electric charge
  9. 14. energy is neither created nor destroyed, it just changes into different types of energy
  10. 15. a combination of two or more elements or compounds which have not bonded together, each element or compound keeps its own properties.
  11. 18. frozen leftovers from the formation of the solar system composed of dust, rock, and ices.
  12. 19. sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system.
  13. 20. a substance that is made up of more than one type of atom bounded together.
  14. 21. is the difference in electrical potential between two points
  15. 25. a theory in which Earth is the center of our solar system.
  16. 26. a surface or line that is curved outward.
