Answer Details
Bi-metallic strips are made of two different metals bonded together, with different coefficients of thermal expansion. When the strip is heated, the two metals expand at different rates, causing the strip to bend. This bending action can be used to control a switch, which is the basis for a thermostat. As the temperature changes, the bi-metallic strip bends, causing the switch to turn on or off, controlling the heating or cooling system. Therefore, the correct answer is "a thermostat".
