4. To calculate the gravitational potential energy of a statue on a 10-meters-tall platform, you would have to know the statue's ______________

5. When a match is struck, the chemical energy stored in the match's head is converted to _____________ and _____________ energy.

6. Heat can be transferred through ______________. ______________, or _________?

7. The Law of Conservation of Energy states that ____________________________ _

8. "You can't get more energy out of something than you put into it" is a statement of?

9. T or F? Living things show that the concept of entropy is not true.

10. Explain why mines dug deep within the earth are often quite hot.

11. What kind of energy does not do work?

12. Sir Marvin decided to improve the destructive power of his cannon by increasing the size of his cannonballs. Sir Seymour kept his cannonballs the same size, but improved his powder to provide more velocity.

a) Which knight will have the more destructive cannon? Why?

b) Jupiter is a more massive planet than either Saturn or Earth. Saturn is more massive than Earth. On which planet would an astronaut weigh the most?

13. T or F? Radiant energy is generated by a petunia on Tuesday.

Part H: C

Review:

1. joules

2. c

3. kinetic energy

4. mass

5. heat and light

6. conduction, convection, or radiation

7. the amount of energy in the universe is constant / energy can neither be created nor destroyed

8. Law of Conservation of Energy / Impossibility of Perpetual Motion

9. F

10. The earth's core.

11. Potential energy.

12. Nice to know.

a) Sir Seymour. The kinetic energy equation has velocity squared. Increasing velocity is much more destructive..

b) Jupiter. Weight is gravity acting on mass. Gravity increases with mass. So  Jupiter.

13. True.

14. Second Law of Thermodynamics describes heat flow from hot to cold objects. So, for the refrigerator to work, it needs to steadily expell hot air or objects inside won't cool as they releases heat to the surrounding air inside the refrigerator.
