Two students carry out different experiments to compare the abilities of different metals to conduct thermal energy.
In experiment 1, the bar is heated for one minute and the length of wax strip that melts is measured.
In experiment 2, the bar is heated and the time taken for the pin to drop off is measured.
What happens to each of these measurements when a better conductor of thermal energy is tested?
