  1. Matter, Temperature, Phase Changes, Pressure/ Buoyancy, and Thermal Energy

  2. Double Jeopardy Jeopardy!

  3. Answer: The Measure of the average kinetic energy of the individual particles in an object What is temperature? Temperature$100

  4. Answer: When you remove most of water’s thermal (kinetic) energy this happens. What is freezing? Temperature $200

  5. Answer: The freezing point of a substance is the same as its _______ point What is melting? Temperature $300

  6. Answer: If two glasses of boiling water are at the same temperature, why would their thermal energy be different? Thermal energy is the measure of movement of molecules plus the amount of molecules… one glass is bigger. Temperature $400

  7. Answer: Explain why being burned by steam can cause more damage than being burned by a similar quantity of hot water at the same temperature. Heat causes thermal energy to transfer into you. Steam has much more kinetic energy then water. Your body is absorbing that extra energy. Steam also condenses on your skin. Temperature $500

  8. Answer: Which state of matter has the LEAST thermal energy? What is a solid? Matter$100

  9. Answer: Which state of matter has a definite volume but NO definite shape? What is a liquid? Matter $200

  10. Answer: Describe two ways an amorphous solid is different from crystalline solid . 1. Amorphous solids don’t have regular atomic patters, crystalline solids have patterns called crystals. 2. When heat is added, amorphous solids just get softer; crystalline solids have crystals so they fight the change of state(Solid, to Liquid, to Gas) Matter$300

  11. Answer: The higher the viscosity of a fluid, the _____________ it flows. What is slower? Matter $400

  12. Answer: Formula M=V X D Aluminum has a density of 2.7 g/cm3. What is the mass of a solid aluminum cylinder with a volume of 1,000cm3? 1,000cm3 X 2.7 g/cm3= 2,700g Matter $500

  13. Answer: This is the total energy of all the particles in a substance. What is Thermal Energy? Thermal Energy Vs Heat$100

  14. Answer: This is the movement of energy from a warmer object to a cooler object. What is heat? Thermal Energy Vs Heat $200

  15. Answer: The more thermal energy a substance has, the more ______________ it has. What are particles? Thermal Energy Vs Heat $300

  16. Internet Answer: Heat is measure in a unit called _______________ . What joules? Thermal Energy Vs Heat $400

  17. Internet Answer… starts with a C: A jar of HOT green water is placed into an aquarium full of COLD water. The HOT green water begins to rise out of the jar to the top of the aquarium, spread out, and fall back down. Name the type of heat transfer. What is convection? Thermal Energy Vs Heat $500

  18. Answer: True or false, the pressure inside the tires is greater after it has been driven on for a few hours than at the beginning of a trip? Phase Changes $100 True

  19. Answer: Solid to Gas. What is Sublimation? Phase Changes $200

  20. Phase Changes $300 Answer: Fog on a mirror. What is Condensation?

  21. Answer: Two types of vaporization. What are evaporation and boiling? Phase Changes $400

  22. Answer: When a substance’s thermal energy changes by a sufficient amount, it ____________. What is changes state? Phase Changes $500

  23. Answer: Why is an air bag used to prevent injury vs. you hitting the dash? The volume (space between atoms) of air is high so you can compress air easier than solids. So air absorbs more of the force from the crash. Pressure and Buoyancy$100

  24. Answer: Why would you want to use snow shoes when crossing deep snow? Pressure is force divided by area… snow shoes increase the area, this causes the pressure to decrease. Pressure and Buoyancy$200

  25. Answer: Blimps filled with helium float in air, what does that say about its density vs. oxygen, nitrogen, and carbon dioxide? It says helium atoms are less massive (lighter) than same amt of other a atoms increasing the buoyant force, causing them to float. Pressure and Buoyancy$300

  26. Answer: Explain how ships made of materials that are denser than water are able to float. They have large wide bottoms which allow for a greater surface area. We know that is a force is exerted over a larger area, the pressure decrea Pressure and Buoyancy$400

  27. Answer: Smath 16,170N X 65cm3= 210N . Pressure and Buoyancy$500 F=MXA

  28. Final Jeopardy

  29. Final Jeopardy! Short Answer: Write your answer on a sheet of paper

  30. Short Answer When heat flows from one substance to another, what happens to the temperature of the substance giving off the heat and to the temperature of the substance receiving the heat?

  31. Short Answer • The temperature of the substance giving off the heat decreases while the temperature of the substance receiving the heat increases.
