Question

In this Virtual Lab you will use a scigentific method and conduct a controlled experiment to determine how color affects heat absorption. A controlled experiment involves setting up two experimental conditions that are exactly the same except for a single factor that the scientist manipulates. The factor you will manipulate in this controlled experiment is color. You will apply a heat source, represented by the 60-watt light bulb, to different colored jackets, and compare the temperature change for each color. White light from the sun or from a lightbulb is a mixture of all colors of the spectrum: red, orange, yellow, green, blue, and violet. When an object is struck by white light, the color you see is the color reflected back to your eyes. For example, blue jeans reflect blue light back to your eyes and absorb all of the other colors of the spectrum. Objects that appear black absorb all colors of light and reflect little or no light back to your eye. Light produces heat and is used in this Virtual Lab to investigate the question “how does color affect heat absorption?” What is the constant
