To show different liquids have different thermal expansions. Five graduated glass bulb tubes are supported in a galvanized iron water trough by a support frame. Bulbs are of approx. 35 mm diameter with stem of 400 mm length.

To determine the co-efficient of absolute expansion of mercury. Glass tubes with vertical limbs contained within glass jackets approx. 460 x 25 mm height x diameter, are closed by bungs and fitted with inlet and outlet tubes. Upper ends of these vertical limbs are angled on emergence from the jackets to produce two short, adjacent limbs placed against a silvered glass scale 0 to 12 cm x 1 mm. Mounted on stand 610 x 230 mm, height x width. Overall height 750 mm approx., supplied without mercury.

Demonstrates the difference in thermal conductivity of two different materials. The kit consists of two identical blocks, one made of aluminum and other made of plastic. When an ice cube is placed on aluminum it turns into water in seconds, while on plastic block, it melts slowly. The aluminum block has a larger heat capacity and a higher thermal conductivity, while the plastic block has lower values of both parameters. With instructions.

To observe heat transfer under different conditions by measuring the temperatures of the insulated containers before and after connecting them with the metal bar. Consists of two insulated containers, two thermometers and a metal bar and instruction manual.
