How will you show that the given material is a conductor of heat or not?
Answers
Answer:
I would compare the material to others of similar size and weight. As to how to do this at home? I would fashion a piece into a strip several inches long and wide and thick enough to be stretched between a beaker ( pot, bucket, whatever) and a thermometer to which I could attach each end of the material being tested. If it were too limp to stretch without touching something in the middle, then all comparisons would have to be performed with an identical length of material touching the same surface at the same point between the heat source( a beaker of warm water, for example)!, and the thermometer. The other piece of equipment you would need would be a timer ( stopwatch, if possible) . To perform this home eeriment. You would set up your material to be tested so that it was firmly attached to the thermometer and start the timer as you put the other end into the warmer water. The material that conveys the highest thermometer reading the fastest is the most conductive.
In a laboratory the theory is the same, but the testing tools should be much more accurate. You could, in theory, by measuring everything, do the math to find a close approximation of the heat conductance of the materials tested.
