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.
1. 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.






2. 1.25 kg/m^3






3. The change in internal energy= the heat absorbed- the work done

9. A disturbance that moves through something






10. How much torque it takes to get an object rotating






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






12. Decreases






13. Are wider at the base (which lowers their center of gravity)






14. The first to do experimental studies of the laws of motion and was Imprisoned by Pope Urban VIII in 1633 for advocating the Copernican theory - also know as the heliocentric theory - that the earth was a planet revolving around the sun.






15. It increases






16. Force per unit area






17. P + density x g h
