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






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






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






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






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