Subjects : science, literacy
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.

27. You cant get as much out as you put in






28. If energy is transferred and the internal energy of system B decreases by some amount then the internal energy of system A must incrase by the same amount.






29. The total disorder of an object






30. You can't get more work out than the energy you put in
