18. Concept Map Below is a concept map on theenergy changes that occur when a personjumps upward. Copy and complete themap by indicating the type of energy—kinetic, potential, or both—the person hasat each of the following stages: halfway up,the highest point, halfway down, and justbefore hitting the ground.21. Determine If heat flows in only one direction,how can hot and cold liquids reachroom temperature as they sit on a table?22. Explain why the walls of houses often arefilled with fiberglass insulation.23. Determine the forms of energy involved ineach of the following situations—a logburns in a fireplace, a ball is dropped,sunlight falls on the leaves of a tree.24. Explain why a blanket is a better conductorof heat when it is wet than when it is dry.just after jumpingKineticEnergy19. Explain why the air feels cooler on a windyday, than on a calm day, even though theair temperature is the same.25. Design an Experiment to determine how quicklythe temperature of different materialschanges as they absorb radiant energy. Usethe following items—three different colorsof construction paper, three thermometers,and a sunny window or a heat lamp.Use the table below to answer question 20.Kinetic Energy of a BallSpeed of Ball (m/s)Kinetic Energy (J)5 2.510 10.015 22.520 40.025 62.530 90.020. Make a Graph Using the data in the tableabove, graph the kinetic energy of the ballon the y-axis and the speed of the ball onthe x-axis. Describe the shape of your graph.How does the kinetic energy change whenthe speed doubles? How does the kineticenergy change when the speed triples?red.msscience.com/chapter_reviewUse the table below to answer question 26.Fahrenheit and Celsius TemperaturesCelsius Temperature (°C)Fahrenheit Temperature (°F)100 21250 1220 322513505826. Temperature Scales Graph the data in thetable with the Celsius temperature on thex-axis and the Fahrenheit temperature onthe y-axis. From your graph, determine thetemperature that has the same value on bothtemperature scales.CHAPTER REVIEW 189
