Name_______________________________ Energy, Heat, and Temperature Test Study Guide 1. Energy has different forms. The two basic kinds of energy are potential energy and kinetic energy. Energy is the ability to do work. Work is the force that causes an object to move. Power is the rate at which the work is done. Potential energy is the stored energy of an object based on its position. Kinetic energy is the energy an object has in motion. Use your knowledge of energy to explain the following: a. How are energy, work, and power related? b. What happens when a bowling ball hits a bowling pin? Explain the energy used and how it is transferred. 2. What two factors affect an object’s kinetic energy? 3. What happens to an object’s kinetic energy as its velocity increases? 4. What does the law of conservation of energy say? 5. Which has a greater gravitational potential energy a book lifted 1 meter off the ground or the same book lifted 10 meters off the ground? Explain your answer. 6. Give an example of the following types of energy (remember foldable): mechanical energy electrical energy nuclear energy- thermal energychemical energy -electromagnetic energy 7. What are the energy transfers that occur in the following: Electric fantoasterLampwindmill- football player throwing a ballrunner- 8. Draw what the particles look like in water as a gas, water as a liquid, and water as a solid. Water as a gas Water as a liquid Water as a solid 9. What three ways is temperature measured? 10. What is heat? Do objects contain heat? Explain your answer. 11. True or False? Thermal energy will transfer from a warmer object to a colder object. 12. What is temperature? 13. What 3 ways is heat transferred? Give an example of each. 14. You are on a camping trip. It is night and you have built a fire. You and your friends are going to boil some water over the camp fire and make hot chocolate. Explain how the three ways to transfer heat are being demonstrated in this example. 15. A solid has ________________ packed particles. A solid has a _________________ shape and volume. The particles in a solid are in slight motion or _______________________. 16. A liquid has _________________ packed particles. However, the particles can move___________________ over one another. A liquid has a/an ______________________shape and a/an ________________________volume. 17. A gas has particles that are ______________ apart and moving ___________________and _____________________________. 18. Give an example of plasma. 19. Give an example of condensation, evaporation, sublimation, melting, and freezing. 20. What is air resistance? Give an example. 21. Explain how a basketball and a golf ball can hit the ground at the same time when dropped at the same height. 22. What is gravity? Give an example. 23. Conduction, convection or radiation? Explain how you know for each. ____________________ Heat we feel from the sun. ____________________ The heat you feel when you touch a stove. ____________________ The heat you feel when you put your hands ABOVE a fire. ____________________ This is responsible for making macaroni rise and fall in a pot on the stove. ____________________ The reason heating vents are usually placed on the floor of a home. ____________________ Why you use a pot holder when getting the cookie sheet out of the oven. ____________________ Heat you feel from your electric blanket. ____________________ Why the dog lays next to the wood stove.
