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