The expansion or contraction of metals is different at the same temperature. Want to see the step-by-step answer? Find an answer to your question why does the bimetallic strips bend when it been heated 1. add. The different metals form the two sides of the strip expand and contract at different rates when subjected to a temperature change. Why is a bimetallic strip made of brass and Invar curved outside with brass? Bimetallic strips are used as switches in thermostats. When the strip is heated it bends with the brass always on the outside of the curve. When a strip made of iron and copper is heated? By reversing the direction of bimetallic strip and connecting the thermostat so that when it falls below a certain temperature, the bimetallic strip bend in the opposite direction to that of fire alarm to connect the alarm system. The different metals form the two sides of the strip expand and contract at different rates when subjected to a temperature change. As the temperature changes, the bimetallic strip curves more or less tightly (contracts or expands) and the pointer, attached to it, moves up or down the scale. Or cooled, just that it will bend the other way. hcbiochem is right, the thermal expansion of the two metals is different, so … Related Physics Q&A. Why does a bimetallic strip bend with changes in temperature? It's made up of two different metals bonded together, which expand by different amounts as they heat up. The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. The metal has the property of thermal expansion, i.e., the metal expand and contract concerning the temperature. What are the social benefits of a business?

Log in. A bimetallic strip bends when heated because it is composed of two different types of metal. When heating a bimetallic strip, one side of the metals expands faster than the other, making it … How does a bimetallic strip work in a fire alarm? 1. One may also ask, which way does a bimetallic strip bend? The metal wit… It is formed when two metals of different linear expansivitiesare riveted together e.g. Join now. The different expansions force the flat strip to bend one way if heated… The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. How much does it cost for elbow dysplasia surgery on a dog? Basically, bimetallic strip is a mechanical element which can sense temperature and transform it into a mechanical displacement. The metal with the higher coefficient of thermal expansion is on the outer side of the curve when the strip is heated and on the inner side when cooled. For example, for brass and steel, the coefficients of linear expansion are: Brass: 19 x 10-6 /°C Steel: 11 x 10-6 /°C . A bimetallic strip is used to convert a temperature change into mechanical displacement. A bimetallic strip bends when heated because it is composed of two different types of metal. The examples shown are straight strips, but bimetallic strips are made in coils to increase their sensitivity for use in thermostats. ... Heat Transfer. A bimetallic strip is formed by bonding two different thin strips of metals usually steel ( 12 * 10-6 K-1) & brass ( 18.7 * 10-6 K-1), or copper ( 16.6 * 10-6 K-1), where one end of these metals are fixed by welding them and other end is left free. What happens when you heat a bimetallic strip? Are crockpot liners the same as oven bags? A bimetallic strip bends when heated because it is composed of two different types of metal. The only way the two metals can stay bonded while expanding at different rates, is for strip to bend, one side becoming longer than the other. bi-metalic strips bend when heated Two metals making up the strip have different rates of expansion, so as heat is applied and the metals expand, one metal will expand faster than the … bi-metalic strips bend when heated Two metals making up the strip have different rates of expansion, so as heat is applied and the metals expand, one metal will expand faster than the other, causing that side to grow longer faster than the other side. Beside above, how are bimetallic strips useful? Why does a bimetallic strip bend with changes in temperature? Why does a bimetallic strip bend with changes in temperature?
