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 composition of glass






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

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






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






22. The process of heating glass to make it stronger






23. Propane and ethane extracted from crude oil






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