- 10. Multiple ChoiceHot objects begin to cool as-cooler air is transferred to the hot object.thermal energy in the object is transferred to the surrounding air.atoms in the object react with the oxygen in the air.thermal energy in the object cancels out energy in the air
- 11. Multiple ChoiceThe heat from a hot burner to a pot is transferred by ______.convectioninsulationradiationconduction
- 12. Multiple ChoiceThe way the heat is moving from the hot coffee is called...convectionradiationinsulationconduction
- 13. Multiple ChoiceInsulation is used in the walls of a building to ____.trap solar energykeep thermal energy from moving through the wallsconduct thermal energykeep cold air from moving through the walls
- 14. Multiple ChoiceWhy do you want to live in a home with good insulation during the cold winter months?The insulation will keep you cool during winter.If there is good insulation, the thermal energy will not be able to move easily from inside the warm home to the cool areas outside the building.If there is not good insulation, the air inside the home will become too hot.A house with good insulation will keep the warm air in the attic.
- 15. Multiple ChoiceWhen a popsicle melts, the particles _____.gain thermal energy and speed upthere are no particles in popsicleslose thermal energy and slow downstay the same
- 16. Multiple ChoiceWhich is more dense?Hot LiquidCold Liquid
- 17. Multiple ChoiceWhat type of material makes the best conductor?FoodWoodStyrofoamMetal
- 18. Multiple ChoiceWhat type of material makes the best insulators?AluminumCopperStyrofoamMetal
- 19. Multiple ChoiceHeat and Temperature are the same thingTrueFalse
- 20. Multiple ChoiceWhat is temperature?How hot or cold something isa number on a thermometerwhat I have when I am sickanything about 30 degrees
- 21. Multiple ChoiceWhat is an insulator?Something that does NOT absorb heat very well.Something that absorbs heat.
- 22. Multiple ChoiceWhat is a conductor?Something that does NOT absorb heat very well.Something that absorbs heat.
- 23. Multiple ChoiceHeat passes from...High to lowCold to hotHot to coldHeat cannot be passed
- 24. Multiple ChoiceExplain the difference between conduction and convection.Conduction involves heat going in all directions while heat rises with convection.Heat moves in all directions for convection, but it rises for conduction.Heat rises for convection and travels thru liquids and gases. Conduction travels thru solids and liquids but must be touching.Thermal energy travels thru solids for both conduction and convection; however, conduction involves direct contact.
- 25. Multiple ChoiceIdentify and explain the different types of heat transfer (convection, conduction, radiation) occurring in the following scenario. Chris went on a camping trip. During the day it was so hot that he got sunburn. When it was time to go to his campsite, he noticed smoke in the air. His father had started a fire and he felt the heat as he walked by. In the morning while his mother was cooking breakfast he accidentally touched a hot pan and got burned. Although this was the case he still had a lot of fun on the trip.Sunburn = radiation;
Smoke rising = convection;
Feeling fire = radiation;
Touching hot pan = convectionSunburn = radiation;
Smoke rising = conduction;
Feeling fire = radiation;
Touching hot pan = conductionSunburn = radiation;
Smoke rising = convection;
Feeling fire = radiation;
Touching hot pan = conduction - 26. Multiple ChoiceThe average kinetic energy in an object.convectiontemperatureHeatradiation

- 29. Multiple ChoiceWhat type of heat transfer is seen in the picture?The sun melting the earthConductionConvectionRadiation
- 30. Multiple ChoiceThe energy transferred between objects at different temperaturesThermal energyHeatTemperature
- 31. Multiple ChoiceWhat is thermal energyThe sunThe total amount of energy from the movement of particles in matterThe ability to do workSome science thing
- 32. Multiple ChoicePans A & B shown above have been on a hot stove for 10 minutes. Pan A has a metal handle and pan B has a plastic-coated handle. Which handle would be hotter?___________ Why?_________________Pan A because the metal is a conductor of heat.Pan B because there is an insulator on the pan.Pan A because there metal is an insulator.Pan B because the metal conducts heat.
- 33. Multiple ChoiceThermometers work because liquids ____ when heated.turn redshrinkexpandevaporate
- 34. Multiple ChoiceIn the Kelvin temperature scale, O degrees K is the lowest temperature that an object can have, known as____.volume of zeronegative temperatureszero caloriesabolute zero
- 35. Multiple ChoiceWhen an object is cooled, its molecules slow down and move closer together, causing the object to _____.shrink or contractexpand or move apartsqueeze into a solidbecome a gas
- 36. Multiple ChoiceThe amount of thermal energy needed to raise the temperature of 1 kg of materials by 1 degree Celsius is called the ____.thermal pollutionconductionconvectionspecific heat
- 37. Multiple ChoiceThe energy that a moving object has that increases when the speed of that object increases is called ____.potentialthermalkineticscientific
- 38. Multiple ChoiceTrue or false? Heat will stop when equilibrium is reached.TrueFalse
- 39. Multiple ChoiceWhich sentence explains why a cold metal spoon placed in a pot of boiling water becomes hot?Thermal energy is transferred from the spoon to the water.Thermal energy is transferred from the water to the spoon.Thermal energy in the water is transformed into kinetic energy in the spoon.Thermal energy in the spoon is transformed into kinetic energy in the water.
- 40. Multiple ChoiceDarth Vader is using a light saber. The light saber is transfering heat through-ConductionConvectionRadiation
- 41. Multiple ChoiceAn ice cube feels cold in your hand because:your hand is an insulatorheat flows from your hand to the ice cubecold flows from the ice cube to your handthere is friction between your hand and the ice cube
- 42. Multiple ChoiceIf you place a cold cup of water in the direct sunlight on a hot day, what change will take place in the thermal energy of the particles that make up the water?The particles will remain the same.The solar energy will cause the particles will slow down because the sun will make the water warmer.The particles will become smaller when the sun's energy heats the water up.The solar energy will cause the water to warm up. This will cause the particles of water to change from moving very slowly-less thermal energy (when cold) to moving quickly as they gain thermal energy (warm up).
