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.
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.
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.
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.
Double-Wall Calorimeter with 1.5 ohm heating coil and 4 mm standard terminals for electrical connections. Complete with insulated stirrer and single-hole rubber stopper.
Operates on 6-V DC. Instructions included.
