No. DSS/PH/077 DESCO COMPOUND BAR (COMPOUND STRIP) To demonstrate unequal expansion in different metals on heating. Highlights the role of temperature and materials in practical applications such as in thermostats. Consists of a laminated strip of two different metals fitted in a wooden handle. The strip is about (l x w), 200 x 10mm. Due to differences in the co-efficient of linear expansion of both metals, the laminated strip bends dramatically on heating.
