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 virgin aluminum that is still in use






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






3. Famous hydroelectric dams






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

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






11. Mineral from which industrial aluminum is obtained.






12. Amount by which recycling paper reduces air pollution






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






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






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






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






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






18. Percent composition of glass






19. Percent of landfill material that is waste paper






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






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






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






23. Percent of aluminum that is recycled in California






24. Percent of code 1 plastics that are recycled






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






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






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






28. Percent of glass beer and soft drink bottles that have been recycled in the US






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






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






31. 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






32. Melting point of glass






33. Percent of aluminum that is recycled in the US






34. The identification code used for different types of plastic resin






35. Percent of California's energy that comes from hydroelectric plants
