DESCRIPTION
Compare the thermal conductivities
of diamond and cubic zirconia by pressing them against an ice
cube. The diamond will conduct the heat from your hand
better and melt farther into the ice than the cubic zirconia.
Cubic
zirconia is an insulator (k = ~0.05 W/m-K), whereas diamond has
one of the largest thermal conductivities of any material
(500-2500 W/m-K).
