Webfigure 1: bimetallic strip. When heated, copper expands more than iron, and to allow this the strip bends with copper on the outside (Figure 2). figure 2: bimetallic strip when heated. … WebThe bimetallic thermometer uses the bimetallic strip which converts the temperature into the mechanical displacement. The working of the bimetallic strip depends on the thermal expansion property of the metal. The thermal expansion is the tendency of metal in which the volume of metal changes with the variation in temperature. pump house surgery repeat prescription
