Hb-1 Expansion
Aim
To demonstrate and compare the thermal expansion of different metals.
Apparatus
- Expansion apparatus
- Aluminium, Brass, Copper and Mild steel expansion rods
Thermal Expansion Apparatus.
Description
The apparatus consists of a cast iron base with two vertical supports which hold the metal expansion rod. The pointer is zeroed by the adjusting screw illustrated and the burners lighted beneath the rod.
Expansion of the rod causes deflection of the pointer and this deflection may be compared for the different metals for the same time interval.
