Chapters 9 & 10 review

  1. 1. Chapters 9 & 10 Review
  2. 2. <ul><li>Force that causes protons and neutrons to be attracted to one another. </li></ul><ul><li>Force that normally causes protons to repel from each other. </li></ul><ul><li>Short; Long </li></ul><ul><li>4. When the strong force is not large enough to hold a nucleus together, the nucleus can decay and give off matter and energy. </li></ul>
  3. 3. <ul><li>5. Nucleus with the same number of protons but different number of neutrons…it’s due to radioactivity. </li></ul><ul><li>6. The amount of time it takes for half of the nucleus in an isotope to decay. </li></ul><ul><li>7. Alpha particles, beta particles and gamma rays </li></ul>
  4. 4. <ul><li>8. The process of changing on element into another through nuclear decay. </li></ul><ul><li>9. Made up of 2 protons and 2 neutrons </li></ul><ul><li>10. An electron that is given off from a nucleus during radioactive decay. </li></ul>
  5. 5. <ul><li>11. Form of radiation called electromagnetic waves. </li></ul><ul><li>12. Alpha; Gamma </li></ul><ul><li>13. Used to detect alpha or beta particles. </li></ul><ul><li>14. holds superheated liquid, which doesn’t boil unless the particles moving through it…the liquid will boil. </li></ul>
  6. 6. <ul><li>15. Device that measures radioactivity by producing an electric current when radiation is present. </li></ul><ul><li>16. The process of splitting 1 large nucleus into 2 smaller nuclei. </li></ul><ul><li>17. An ongoing series of fission reactions. </li></ul>
  7. 7. <ul><li>18. The amount of fissionable material required so that each fission reaction produces 1 more fission reaction. </li></ul><ul><li>19. The process of combining 2 smaller nuclei into 1 large nucleus. </li></ul><ul><li>20. Sun and stars; it’s found only in extreme high temperatures </li></ul>
  8. 8. <ul><li>21. Resources that can not be replaced by natural processes as quickly as they are used up. </li></ul><ul><li>Fossil fuels </li></ul><ul><li>22. Fuels formed from decaying remains of ancient plants and animals. </li></ul>
  9. 9. <ul><li>23. Coal- solid </li></ul><ul><li>Petroleum- liquid </li></ul><ul><li>Natural gas- gas </li></ul><ul><li>24. Contains more impurities so there are more pollutants released when burned…most abundant fossil fuel. </li></ul>
  10. 10. <ul><li>25. Highly flammable liquid form of fossil fuel. </li></ul><ul><li>26. Gas form of fossil fuel…it contains more energy than petroleum or coal. </li></ul><ul><li>27. Energy source that is replaced as quickly as it is used. Solar, hydroelectric, Wind, Geothermal </li></ul><ul><li>and Biomass. </li></ul>
  11. 11. <ul><li>28. When energy is released when the nucleus of an atom breaks apart (nuclear fission). </li></ul><ul><li>29. Uses the energy from controlled nuclear reactions to generate electricity. </li></ul><ul><li>30.-Low amounts of carbon dioxide...little effect on global warming </li></ul><ul><li>-Generates large amount of electrical energy </li></ul>
  12. 12. <ul><li>31. Uranium, Water from reactor must be cooled before it’s released into streams and nuclear waste. </li></ul><ul><li>- Nuclear waste- radioactive by-product that results when radioactive materials are used. </li></ul><ul><li>32. Energy from the sun </li></ul><ul><li>33. converts solar energy into electricity. </li></ul>
  13. 13. <ul><li>34. Electricity made from energy of moving water. </li></ul><ul><li>35. Energy from the wind. </li></ul><ul><li>36. Thermal energy that is contained in hot magma. </li></ul><ul><li>37. Fuels from organic matter (wood, sugar cane fibers, rice and animal manure). </li></ul>
