1. What is being described in the following situation: the ability to do work or to produce heat transfer?

2. List from among the following those examples that are not examples of kinetic energy: a falling rock, a stick of dynamite, a speeding bullet, or a flow of electric current?

3. From the standpoint of classification, what are the two most common forms of energy?

4. Which one of the following does not belong with the other three: a leaf falling from a tree, electricity flowing through a wire, a bullet fired at high velocity?

5. What does the chemical energy in a candy bar and a slice of bread represent?

6. Which of the following would be examples of high-quality energy: electricity, heat in the ocean, nuclei of uranium-235, coal, gasoline?

7. During a nuclear fission reaction, what does each fission releas?

8. What is used to fuel conventional nuclear -fission reactors ?

9. List from among the following those that are products of a fusion reaction: tritium, helium, alpha particles, and deuterium..

10. What is an uncontrolled nuclear fission reaction?

11. What is being described: a nuclear change with release of energy from combining two nuclei of isotopes of light elements?

12. What is the source of thermonuclear weapons' energy?

13. What are the products of a a nuclear fusion reaction?

14. Which of the following statements are true? Energy can be converted from one form to another. Energy and matter can generally be converted into each other. Energy input always eaquals energy output. The laws of thermodyamics can be applied to living systems.

15. Identify the law of energy which tells us that it takes energy to get energy.

16. TRUE/FALSE The quality of energy available after work is performed will always be lower than the initial eenrgy quality.

17. Which of the following are examples of the second energy law? Ninety-five% of the electrical energy flowing through an incandescent light bulb is given off as heat. Most of th e chemical eenrgy in the food we eat is given off as waste heat. 90% of the high-quality chemical energy in gasoline burned in automobiles is degraded to low-quality heat.

18. Which of the following is an accurate description of the relationship between energy and matter: We can recycle both mater and enegy. We can cycle neither matternor energy. We can cycle matter but not energy. We can cycle energy but not matter.

19. TRUE/FALSE In any energy transformation some of the energy usually ends up as heat energy that flows into the environment.

20. TRUE/FALSE: Energy can be neither created nor destroyed is applicable to the second law of energy.

21. Which one of the following practices does a high-waste society sustains economic growth: minimizing the rate of energy resource use, minimizing the rate of energy and matter resource use, maximizing the rate of energy resource use,or by maximizing the rate of energy and matter resource use?

22. Which one of the following is the most logical way to cope with the problem of limitations imposed by the three basic physical laws governing matter? Shift to nonpoluting nuclear fusion power. Use and waste less energy and matter. Increase the output of low-quality heat. Increase the input of high-quality energy.

23. Amoong the following, which would characterize low-waste societies? Use energy more efficiently. Shift to perpetual and renewable energy sources. Recycle and reuse most matter than is now discarded. Creat goods with a short life cycle to increase recycling.
