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






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






3. Percent of landfill material that is waste paper






4. Percent of aluminum that is recycled in the US






5. Percent of code 1 plastics that are recycled






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






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






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






9. Melting point of glass






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






11. 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






12. The number of times paper can be reused.






13. The five most used forms of renewable energy






14. Famous hydroelectric dams






15. Percent of aluminum that is recycled in California






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






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






18. Refers to the removing of oxygen from a metal ore by burning it with a carbon - based fuel or electrolytically.






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






20. Percent composition of glass






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






22. Another word for virgin






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






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






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






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






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






28. 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.






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






30. Accounts for 38% of aluminum consumption






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






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

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






36. Percent of gasoline that must be ethanol in California






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






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






39. The simplest plastic polymer.






40. The process of heating glass to make it stronger






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