Purpose To observe the curious heat transfer abilities of different surfaces Apparatus defrosting tray 3 second defrosting tray wrapped tightly in aluminum foil white Styrofoam plate black Styrofoam plate (or a white plate blackened completely using a felt-tip pen) 4 ice cubes of similar size paper towel ----_________ Discussion If you walk around inside your house with bare feet, you probably notice that a tile oor feels much colder than a carpeted oor or rug. It is hard to believe that they might actually have the same temperature. The tile feels colder because it is a better conductor than carpet. Heat is conducted from your warmer feet to the cooler oor faster when the oor is tile than when the oor is carpet. So your feet are cooled faster by tile than they are by carpet at the same cool temperature. In this activity, you will see which kinds of surfaces transfer heat most rapidly. Procedure Step 1: Set the defrosting tray, defrosting tray covered in aluminum foil, white Styrofoam plate, and blackened Styrofoam plate on your table. Figure 1. e. defrosting tray. b. defrosting tray covered In aluminum foil. c. white Styrofoam plate. d. blackened Styrofoam plate Which surfaces feel colder and which ones feel warmer? (Just touch a corner; do not transfer too much of your own body heat to any of the objects.)
