LINEAR EXPANSION APPARATUS

LINEAR EXPANSION APPARATUS:

Specifications:

• Demonstrates the linear expansion of solids and allows comparison of expansion rods of different materials.
• Comprises cast metal end supports mounted at each end of a horizontal metal reservoir.
• Open at the top, that can take any liquid fuel such as alcohol.
• One of the end supports has a scale with pointer needle on the outside to indicate the expansion in the rod.
• Expansion rods supported in the holes near top of both the end supports and can be clamped at the end opposite to that of scale pointer.
• Burning of fuel in the reservoir causes rod at the top to expand, which in turn pushes the pointer needle showing deflection in the scale.
• Includes three expansion rods.
• 1 each of brass, copper and aluminum
