CSET Renewable Sources Of Energy And Recycling

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Percent of aluminum that is recycled in California






2. The five most used forms of renewable energy






3. Material from discarded consumer products. Source of 1/3 of the aluminum used in the US






4. Have a structure with links between the chains - forming a rigid - three - dimensional network. When thermoset polymers are heated - they chemically decompose and cannot be reformed into different shapes.






5. Percent composition of glass






6. The use of the kinetic energy in moving water such as rivers or tidal currents to generate electricity. The most widely used form of renewable energy






7. The process by which aluminum oxide is obtained from bauxite






8. Percent of California's energy that comes from renewable resources (excluding hydroelectric plants

9. (recycling) The original product - not made out of recycled materials






10. The ability to meet humanities current needs without compromising the ability of future generations to meet their needs






11. Thermoplastics - all can be recycled - but not all are.






12. Percent of materials used to make new bottles and jars that can be cullet






13. Scrap material generated by a company and reused or recycled by that company






14. Air movement that can be harnessed to give mechanical energy or electricity.






15. The largest damn in the US and the third largest hydroelectric facility in the world






16. Mineral from which industrial aluminum is obtained.






17. Percent of glass beer and soft drink bottles that have been recycled in California






18. Have relatively linear molecular structure. When they are heated above their melting point - they soften and flow like a liquid.






19. Percent of aluminum that is recycled in the US






20. Propane and ethane extracted from crude oil






21. In China - still being built - will produce the most hydroelectric power in the world






22. Accounts for 38% of aluminum consumption






23. Made or recovered from both new and scrap product






24. The simplest plastic polymer.






25. Famous hydroelectric dams






26. Built to control flooding on the Nile; provided about half of Egypt's electricity at the time it was built






27. A kind of polymer that comes in two parts. When the two parts are mixed - they fuse together and harden.






28. Was the largest dam at the time it was built; still one of the largest hydroelectric plants in the US.






29. Percent of plastic produced in the US that is recycled






30. Radiation from the Sun that can be used directly for heating - or it can be converted to electricity.






31. Amount of energy required to make recycled paper products.






32. Percent of paper consumed in the US that was recovered for recycling






33. The process of heating glass to make it stronger






34. Amount of energy required to make recycled glass products.






35. Reuse of bottles and crushing of collected glass bottles to be re - melted






36. On border of Brazil and Paraguay - produces enough energy to fulfill all of California's needs.






37. Amount by which recycling paper reduces air pollution






38. Scrap generated by a company that cannot or will not use it. The company sells this scrap on the secondary market






39. Percent of code 1 plastics that are recycled






40. Percent of fiber used to make new paper products in the US that comes form recycled sources.

42. Melting point of glass






43. The number of times paper can be reused.






44. Organic material that can be burned to release energy in the form of heat.






45. Percent of virgin aluminum that is still in use






46. Percent of aluminum that is recycled in Brazil






47. The process by which ethane and propane are converted to ethylene and propylene






48. Glass that is crushed and ready to be remelted.






49. Energy derived from the heat in the interior of the earth that can be used to heat buildings or generate electricity.






50. Amount of energy required to make a ton of recycled aluminum.
