The Science Behind Bimetallic Strips
A bimetallic strip consists of two different metals bonded together. When heated, the metals expand at different rates, causing the strip to bend.
In this demo:
- Brass (left side): Expands more when heated (higher coefficient of thermal expansion)
- Steel (right side): Expands less when heated (lower coefficient of thermal expansion)
This principle is used in thermostats, thermometers, and other temperature-sensitive devices.
