*This instrument is a heat conduction demonstrator, used for middle school physics teaching to demonstrate the difference in thermal conductivity of different solid materials. *In the experiment, the heat storage block is heated, and then the heat conduction rod with the same thickness and the same length in a radiating shape conducts heat outward along the rod, and the large sticks adhered to the pit are turned upside down to show the heat transfer process and the difference of different materials. Thermal conductivity. *Place the instrument on the desktop in a balanced manner, spread a little butter on the concave surface of each heat-conducting rod, and insert a match. The match stick is stuck to the concave in an upright position, and then the heat storage block is heated with an alcohol lamp. After a while, observe the successive dumping of the matches on each heat-conducting rod, and compare the results of the experiment. *After the experiment is completed, after the heat-conducting rod is completely cooled, wipe it clean, oil it and save it, and be careful not to drop the instrument or hit the heat-conducting rod. *We attach great importance to customer experience, so you can contact us if you have any questions, and we will get back to you within 24 hours!
