8. As the kinetic energy of the molecules in a substance increases, the _____ also increases.

9. temperature

10. The transfer of energy as heat caused by the collision of molecules is called

11. conduction.

12. The transfer of energy by the movement of fluids or gases with different temperatures is called

13. convection.

14. Energy from the sun reaches Earth by

15. radiation only.

16. Convection currents rise in air because

17. cool air descends and hot air rises.

18. Which method of energy transfer does not involve movement of matter? convection. radiation. conduction.

19. radiation.

20. How much heat energy will cause the temperature of 7 kg of carbon to increase its temperature by 15 K? The specific heat of iron is 449 J/kg·K.

21. 4.7 × 104 J(47000 J)

22. According to the first law of thermodynamics,

23. the total energy used in any process is conserved.

24. In an air conditioner, a substance that easily evaporates and condenses is used to transfer energy from a room to the air outside. When the substance evaporates,

25. it absorbs energy as heat from the surrounding air.

26. The Fahrenheit temperature scale is defined by what temperatures?

27. Water boils at 212 degrees and freezes at 32 degrees.

28. The energy transferred between the particles of two objects because of the temperature difference between the two objects is called

29. heat

30. Which of the following substances is the best conductor of transferring energy as heat? carbon dioxide gas iron Water rubber

31. Iron

32. Radio waves, infrared radiation, visible light, ultraviolet rays, and X rays are forms of

33. electromagnetic waves

34. A substance used in cooling systems that transfers large amounts of energy as it changes state is called a

35. refrigerant

36. This is a material through which energy can be easily transferred as heat.

37. conductor

38. This is a material that is a poor energy conductor.

39. insulator

40. This is the amount of energy transferred as heat that will raise the temperature of 1 kg of a substance by 1 K.

41. Specific heat

42. This is any device that transfers energy to a substance to raise the temperature of the substance.

43. heating system

44. This is a device that transfers energy out of an object to lower its temperature.

45. cooling system

46. This is the energy transfer as heat between particles as they collide within a substance or between two objects in contact.

47. Conduction

48. This is the temperature at which an object's energy is minimal.

49. Absolute zero

50. This is a device for measuring temperature.
