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 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.
Heavy duty, both ball and ring are mounted on separate handles.
When cool, the 25 mm brass ball passes easily through the matching brass ring; when hot, it won't go through.
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.
A 500 mm long metal rod is supported in a plated brass tube with three tubules for steam inlet, outlet and thermometer.
The tube is mounted on a stand with an adjusting screw at one end and a micrometer screw reading to 0.01 mm on the other, with terminals for connecting a bell or galvanometer to indicate contact.
With copper, brass and iron test rods but without thermometer.
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.
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.
