A bimetallic strip is used in devices like a fire alarm, fans, etc. Thermal expansion is the property of a metal to change its shape or volume with a change in temperature. When temperatures increase, objects expand and become larger and therefore the density decreases. . When the bimetallic strip is heated, the metal with higher thermal expansion will bend more. Which material expands least when heated? Why does the bimetallic strip change shape? The expansion (or contraction) of any material is due to the kinetic energy of its atoms. Since the two metals expand to different lengths, the bimetallic strip is forced to bend or curl towards the side with a lower coefficient of thermal expansion. When the temperature is lower than normal room temperature, the length of the brass will be less than the length of the iron, and so the bimetallic strip will become U-shaped with the brass on the topside. This happens because A. brass expands more than steel B. steel expands more than brass 14. When a material is heated, The increase in energy causes the atoms and molecules to move more and to take up more space that is, to expand. Bimetallic Lugs are mostly useful where an aluminum cable has to be terminated by a copper bus bar or copper contact. 10.A bimetallic strip bends when heated. 11.Temperature Field Simulation in Solidification of Bimetal Composite Pipe with Centrifugal Casting; The bimetallic strip constitutes one of the most trouble-free and durable thermometers. Each metal responds to heat and cold by expanding a specific amount based on the change in temperature. Answer: when a bi metallic strip such as a combination of either iron and brass or steel and copper , brass or copper expands more on heating than iron or steel, thus when the bi metallic strip is heated , one side expands in length ( linear expansion) more than the other causing the strip to ben.
