In the investigation shown, students tested to see how long it takes the two metal
bars to heat up enough to cause the beads of wax to fall off. One student believes
the wax on the lead rod will fall off; his lab partner says the opposite. Assuming that
aluminum has a lower specific heat than lead, which students is most likely correct and why?
A. The pieces of wax on the aluminum rose will off first because of aluminums low specific heat
B. The pieces of wax on lead rod will off first because of leads high specific heat
C. All four pieces of wax will off at the same time because metals are good conductors of head
D. The metals will not heat up enough to cause the wax to fall off because they are dense
