Two cast metal uprights, height 18 cm, fitted with two nickel plated rods supporting expansion bar of length 38 cm.
Expansion bar is fixed to one upright and moves a pointer on the other, when heated With scale reading 0 to 90°, supplied with one each, aluminium, brass and iron expansion bars.
Comprising two castÂmetal uprights linked by a pair of parallel plated metal support rods and supporting an expansion bar at the top. Supplied with expansion bars.
Comprising two cast-iron uprights, height 18 cm linked by two nickel plated rods supporting on expansion bar, length 38 cm fixed to one upright and resting on a friction pointer placed at the other.
Supplied with scale reading 0 to 90 deg and one each of aluminium, brass and iron expansion bars.
Apparatus is fitted on heavy channel base, at one end of which is an adjusting screw, at the opposite end is a micrometer screw reading to 0.01 mm for measuring the expansion.
Supplied with one each of aluminium, brass and iron expansion rods but WITHOUT thermometer.
Consisting of metal rod 500 mm in length and 4.5 mm dia.
enclosed in a well - lagged, metal tube with three tubules for steam inlet, outlet and thermometer.
The metal rod to be investigated is supported in the steam jacket by detachable rubber bungs situated at each end of the tube.
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.
Nickel plated copper calorimeter of 50 x 75 mm lagged and enclosed in an outer vessel of 75 x 100 mm size, with cover having terminals, a heating coil suitable for 3 – 6 V supply and holes for thermometer and stirrer.
With stirrer but without thermometer.
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.
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.
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.
