To study and demonstrate heat absorption and radiation. Consists of two metal concave plates one white and the other painted black with thermometer holders on the back, and in-between is a lamp, heat source. When the lamp is switched on and the temperature is measured of the metal plates, it can be studied which one absorbs heat quicker and more than the other. After the lamp is turned off, we can also study which losses heat quicker. Lamp operates on 12VDC. Base Size 7.75" x 7.75" x 0.5". Metal plates are 3.75" in dia. Total height of unit 5.5". One bulb included, thermometers not included.

Students fill one container with water at room temperature and the other with boiling water. A thermometer is placed in each container and the water temperature in both cups read before heat transfer. The metal bar is then immersed in the cups, and students observe heat lost by boiling water and heat gained in the cooler water. Each kit includes: 2 insulated containers; 2 insulated lids with slots; 1 U-shaped aluminum transfer bar; 2 thermometers 20 degrees to 110 degrees. Additional materials required: low-temperature thermometer.
