Comparing the Specific Heats of Metals II
Description: Equal masses of metals are placed in boiling water, and the temperatures allowed to equilibrate. The hot metals are placed on a track of beeswax and allowed to run down the track, melting the wax as they go. The metal with the higher specific heat capacity goes farther down the track.
