Expansion in physics refers to the increase in volume of a substance due to temperature changes. This concept is crucial in thermodynamics and materials science. Our expansion apparatus helps in demonstrating the effects of heat on different materials, allowing for a practical understanding of thermal expansion.

Key Expansion Tools:

• Thermal Expansion Kits: Demonstrate the linear expansion of solids.
• Bi-metallic Strips: Useful for understanding the concept of thermal expansion in different metals.
