A heavy cast iron stand slotted to carry a stout iron bar, with ten cast iron breaking bars.
Comprising a heavy cast iron frame 340 x 120 x 100 mm with slotted end pillars to carry a stout iron bar.
The bar is threaded at one end for a large tensioning nut and has holes at the other end to accommodate the cast iron breaking bars.
Supplied complete with ten breaking bars.
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.
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.
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.
Copper calorimeter of 75 x 50 mm resting on felt pad inside wooden polished box provided with a brass nickel plated thermometer holder and copper stirrer.
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.
