Coefficient of Linear Expansion
Product Code : JL-LEP-10207
The Coefficient of Linear Expansion apparatus (SKU JL-LEP-10207) is used to verify the coefficient of linear expansion of metals. A test rod sits inside a brass steam jacket; as steam heats it, a dial gauge reading to 0.01 mm records the increase in length, and a thermometer in the attachment tube gives the temperature. With brass, copper and steel rods supplied, the linear expansion apparatus lets students compare metals. JaincoLab supplies it as per DepEd guidelines.
Specifications
The apparatus is specified by its steam jacket, gauge, base and rods: a 500 mm x 25 mm brass steam jacket with inlet and outlet, a thermometer tube with stopper, a rigid aligned base, a 0-10 mm dial gauge reading 0.01 mm and three 4 x 500 mm test rods.

Applications of the linear expansion apparatus
The apparatus is used in heat practicals where students measure a small change in length and calculate a material constant from it. Typical uses are:
- Determining the coefficient of linear expansion of brass, copper and steel
- Comparing how different metals expand for the same temperature rise
- Practising dial gauge reading to 0.01 mm
- Discussing expansion allowances in rails, bridges and pipes
