Give an example of something that transforms electrical energy to light energy. 9. What is “energy of motion”? 10. Why does a light bulb feel hot when you touch it?

Round 3

11. What are the three types of thermal energy transfer? 12. In a pot of soup, most of the soup is heated through which type of thermal energy transfer? 13. When the sun shines on the earth’s surface, which type of thermal energy transfer is this? 14. If you dip a metal spoon in a cup of hot chocolate energy moves from the hot chocolate to the spoon because particles of hot chocolate vibrate particles of the _________________. 15. Why are bridges designed with expansion joints between sections?

Round 4

16. A thermometer is placed in a cold glass of ice water. Describe what happens to the particles of colored liquid in the thermometer when the liquid’s volume decreases causing the line of colored liquid in the thermometer to go down. 17. What is the difference between heath and temperature? 18. How does energy transfer when there is no air? For example, through the vacuum of space? 19. What is the law of conservation of energy? 20. If a car is parked on top of a hill, would adding or subtracting people increase its potential energy?
