Energy can be transformed from one form into another. 1 1 Reviewing Main Ideas Kinetic energy is the energy an object has due to its motion. Kinetic energy increases as the speed of an object increases. Potential energy is stored energy that increases as an object’s height increases.

41. To return to the chapter summary click Escape or close this document. Temperature is a measure of the average kinetic energy of the particles in a material. Temperature The movement of energy from a warmer object to a cooler one is called heat. 2 2 Reviewing Main Ideas Heat can be transferred by conduction, convection, and radiation.

42. To return to the chapter summary click Escape or close this document. The energy stored in chemical bonds is chemical energy. Chemical Energy Chemical reactions can release or absorb energy. Exothermic reactions are chemical reactions that release energy. Endothermic reactions absorb energy. 3 3 Reviewing Main Ideas Changing the temperature and adding catalysts can change the rate of chemical reactions.

43. To return to the chapter summary click Escape or close this document. Question 1 Chapter Review Why does convection usually occur in liquids and gases, but not in solids?

44. To return to the chapter summary click Escape or close this document. Answer Chapter Review In liquids and gases, atoms and molecules are free to move from place to place. As a result, they can transfer energy by moving from a warmer place to a cooler place in a material. In solids, atoms and molecules don’t move from place to place within the solid.

45. To return to the chapter summary click Escape or close this document. Question 2 Chapter Review In an exothermic reaction, heat energy is _______. A. absorbed B. created C. destroyed D. released

46. To return to the chapter summary click Escape or close this document. Answer Chapter Review The answer is D. Exothermic reactions release heat energy.

47. To return to the chapter summary click Escape or close this document. Question 3 Chapter Review How does the Sun’s energy reach Earth? Answer The Sun’s energy reached Earth by radiation. The other forms of heat transfer can’t occur through empty space.

Question 4 Chapter Review One of the reasons the handle of a pan is made of wood rather than metal is that wood does not transfer heat as quickly from the hot pan to your hand. In other words, wood is a poor _______. A. conductor B. coolant C. insulator D. thermometer

49. To return to the chapter summary click Escape or close this document. Answer Chapter Review The answer is A. Wood is a poor conductor of heat energy.

51. To return to the chapter summary click Escape or close this document. Answer Chapter Review The answer is D. Chemical energy is a form of potential energy that is stored in the binds between atoms in a compound.

52. To return to the chapter summary click Escape or close this document. Standardized Test Practice Question 1 Burning is a(n) _______ chemical reaction. A. endothermic B. exothermic C. photosynthesis D. kinetic

53. To return to the chapter summary click Escape or close this document. Standardized Test Practice Answer The answer is B. Because heat is released, the chemical reaction is exothermic.

54. To return to the chapter summary click Escape or close this document. Standardized Test Practice Question 2 The temperature of a material increases when the atoms in the material _____. A. move closer together B. move farther apart C. move faster D. move slower

55. To return to the chapter summary click Escape or close this document. Standardized Test Practice Answer The answer is C. When temperature increases, the atoms are moving faster and have more kinetic energy.

56. To return to the chapter summary click Escape or close this document. Standardized Test Practice Question 3 As the height of a ball increases, its _____ energy increases. A. kinetic B. electrical C. heat D. potential

57. To return to the chapter summary click Escape or close this document. Standardized Test Practice Answer The answer is D. When the height of an object increases, its potential energy increases.

58. To return to the chapter summary click Escape or close this document. Standardized Test Practice Question 4 As water falls from the top of a waterfall, which forms of energy are changing? A. electrical and chemical B. kinetic and potential C. kinetic and electrical D. potential and nuclear

59. To return to the chapter summary click Escape or close this document. Standardized Test Practice Answer The correct answer is A. Kinetic energy is the energy of motion.

60. To return to the chapter summary click Escape or close this document. Standardized Test Practice Question 5 What determines the kinetic energy of an object? A. only its mass B. only its speed C. both its mass and speed D. both its mass and speed as well as its direction

61. To return to the chapter summary click Escape or close this document. Standardized Test Practice Answer The answer is C. Mass and speed are the two factors you need to know to determine the kinetic energy of an object.
