Two rods, X and Y, of the same size have drawing pins fixed along their length with wax. One end of each rod is heated by a flame. The pins on rod X fall off much sooner than the pins on rod Y. What does this show?
- Rod X is a better conductor of heat than rod Y.
- Rod Y is a better conductor of heat than rod X.
- Both rods are equally good conductors of heat.
- Neither rod conducts heat; the pins fall off by radiation only.
