Metal, for experiments on specific heat of different metals, cylindrical metal blocks 1 Kg ± 2%. Each block has a central hole for a special immersion heater and an offset hole for Thermometer.
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.
Consists of a thick brass calorimeter 90 x 65 mm, a bung with steam inlet and outlet tubes, a felt cover and a one liter brass sheet boiler with bung to take the steam tube.
Demonstration Apparatus for Illustration of Thermoexpansion.
A 12 V Halogen bulb is fitted below the bi-metallic strip.
When heated the strip bends upward and breaks the circuit.
To illustrate expansion of metal on heating and contraction on cooling, with steel bar of length 100 x 10 mm and plated brass gauge with a cutout to just accommodate the bar and two holes through which the bar passes when cold.
A metal stand fitted with 0-100 cm x 1 mm vertical wooden scale and supporting a mercury reservoir sliding on a metal rod.
An air thermometer bulb fitted to a bracket can be attached to the other rod at either of two positions.
With U-shaped base.
Complete with 1 meter rubber tubing to connect reservoir to the bulb.
Supplied without mercury.
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.
