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.

EXPANSION OF LIQUIDS APPARATUS (0222)
Demonstrates the different thermal expansion of various liquids thus simultaneous comparison of the volumetric expansion of up to five different liquids. The apparatus consists of five glass bulbs with integrated long tube shaped neck ending in small funnel at the top to facilitate pouring in of liquids, the neck of the bulbs having scale graduated in millimeters. The neck of bulbs supported in a metal frame mounted on a sheet metal trough with the bulbs located inside the trough. Heating the trough with water contained in it provides uniform heating to all the five bulbs through the heated water, and the level of liquids in each bulb can be read along the scale on the neck to indicate its expansion.
