explain electrical and thermal conductivity of metal with one experiment
Answers
Answer:
Procedure
Obtain two beakers (similar or different size), fill one with water and place it on the hot plate.
Place the other beaker on object of similar size to the hotplate as to make the lips of both beakers at the same height (or use a taller beaker)
Bend all the wires 90° on both ends creating 50mm arms and ensure that 1m of straight wire is maintained
Ensure that the bent end of the wire is immersed in the water
Place all three wires of choice on the lips of both beakers as to connect both beakers
Thermal Conductivity Resources Experiments Variations In Material
Use a marker to mark each wire every 200mm or if using candles, melt the bottom of each candle using some source of heat and place the candles at 200mm intervals along the wire
Heat the water using the hot plate for 15 minutes and then take temperature readings at each 200mm intervals
*shorter wires may be used for a faster experiment time if needed, simply make a measurement at every 1/5th of the wire*
