- 14. Multiple ChoiceBlow drying your wet hair.conductionconvectionradiation
- 15. Multiple ChoiceA group of friends gather around a fire to stay warm.conductionconvectionradiation
- 16. Multiple ChoiceWarm air rises and the cool air sinks.conductionconvectionradiation
- 17. Multiple ChoiceIn this experiment, the WARM red dye and the COLD blue dye was placed in the water at the same time. The warm red dye rose to the top while the cold blue dye sank to the bottom.conductionconvectionradiation
- 18. Multiple ChoiceHow is the cat being heated?condensationconductionconvectionradiation
- 19. Multiple ChoiceHow is the man being heated?condensationconvectionconductionradiation
- 20. Multiple ChoiceHow is the teapot being heated?condensationconductionconvectionradiation
- 21. Multiple ChoiceIf two objects have different temperatures, heat will flow from the cooler object to the warmer one.truefalse
- 22. Multiple Choicethe transfer of energy by electro-magnetic waves is calledconductionconvectionradiation
- 23. Multiple ChoiceWhen heat is transferred by the movement of currents within a fluid it is calledconductionconvectionradiation
- 24. Multiple ChoiceThis is a current caused by the rising of heated fluid and sinking of cooled fluid.convection currentconduction currentradiation currentheat current
- 25. Multiple Choice4. Energy will always flow or move from...An area of low temperature to an area of high temperatureAn area of high temperature to an area of low temperatureatoms to molecules
- 26. Multiple ChoiceConvection is the transfer of heat through _____liquid or gascandytables
- 27. Multiple ChoiceRadiation is the transfer of heat through electromagnetic waves which move through space.TrueFalse
False - 28. Multiple ChoiceLow temperature means more thermal energy.TrueFalse
- 29. Multiple ChoiceHigh temperature means less thermal energy.TrueFalse
- 30. Multiple ChoiceHeat is what type of energy?ThermalChemicalPotentialKinetic
- 31. Multiple ChoiceWhat is an insulator?An object that allows heat to pass through easily.An object that is difficult for heat to pass through.
- 32. Multiple ChoiceA conductor is an object that allows heat to pass through easily.TrueFalse
- 33. Multiple ChoiceHeat moves through the atmosphere as air circulates. What causes the circulation of air?Air in the atmosphere is heated by the sun and sinks to the ground.The ground is heated by the sun and then heats the air, causing the air to rise.Air loses heat to the ground and then rises upward to obtain more energy.The sun heats the clouds which forces the cooler air to move away and sink.
- 34. Multiple ChoiceWhat keeps the water at the top of pot of boiling water the same temperature as that of the bottom?Heat from the burner radiates through the liquid and causes even heating.Evaporation heats the water at the top and the eye of the stove heat the water at the bottom.The walls of the beaker reflect heat toward the center, so the water heats evenly.Heated water molecules and steam rise in the pot, carrying heat by convection.
- 35. Multiple ChoiceIn what way does the Sun warm Earth?radiationconvectionconductioncondensation
