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.

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






32. Made or recovered from both new and scrap product






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






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






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






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