| THERMAL CONDUCTIVITY APPARATUS, STAR SHAPED
(0218) |
| For demonstration of differences in the thermal conductivity of five different metal - brass, copper, aluminium, mild steel and stainless steel. These 5 metal rods spread radially outward. equally spaced on each side of hexagonal brass hub, and have a small recess at the other end for holding paraffin wax. The sixth side of brass hub has a metal rod terminating in an insulating handle. On heating the central hub, the wax contain ed in the cavities of different metals melts at different times, implying their different thermal conductivities. |
