Two students perform two different experiments to compare how well different metals conduct thermal energy. In experiment 1, the bar is heated for one minute and the length of wax strip that melts is recorded. In experiment 2, the bar is heated and the time taken for the pin to fall off is recorded. How do these two measurements change when a better conductor of thermal energy is tested?
- Alength of melted wax strip decreases; time taken for the pin to drop decreases
- Blength of melted wax strip decreases; time taken for the pin to drop increases
- Clength of melted wax strip increases; time taken for the pin to drop decreases
- Dlength of melted wax strip increases; time taken for the pin to drop increases
