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.
A glass U-tube of 10 mm diameter the shorter limb of which has a stopcock near top and the longer limb can take a plastic tube.
A scale is provided and can be attached to the shorter limb With red indicator oil but without 2000 ml tall form beaker which acts as a reservoir.
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.
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.
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.
Copper calorimeter 75 x 50 mm with felt insulation, outer vessel of 100 x 65 mm size with a plastic lid having holes for thermometer and stirrer.
A thermometer holder is fixed to the outer vessel. Complete with stirrer.
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.
Specially designed for metal block calorimeters.
Heating element enclosed in a metal tube with two connecting leads which are insulated with heat resistant insulation. 12 V, 50 W.
