Polished aluminum container placed in an outer wooden case with thermometer, plastic top fitted with two terminals for heating coil and a hole for thermometer.
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.
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.
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.
Consisting of a joint less copper calorimeter 75 x 50 mm on rubber supports, spun outer copper vessel of 100 x 75 mm diameter copper lid for outer vessel with central tubule for thermometer and slit for copper stirrer with a looped copper stirrer for the inner vessel.
Fitted on a wooden base cast metal uprights and rod mountings.
A 20-0-20 scale is provided to notice the expansion in rods.
The counter weighted needle is used for easy reading.
A knurling screw is provided for zero adjustment.
Supplied with three metal rods one of each Aluminium, Brass and Steel.
