Thermal conduction experiment. A metal coin and a plastic button on thermochromic paper. The experimenter placed their fingers on both for a short while. When they removed their fingers,the thermochromic paper under the coin had changed colour,indicating a change in temperature. This shows that metal is a good conductor of heat,and plastic is a poor conductor | |
