Description:Two strips of different metals, invar steel and brass, are welded together to form a bimetal strip. Since each metal has a different coefficient of thermal expansion, heating the bimetal strip will result in the metals expanding at different rates, causing it to bend. This type of material is used in some types of thermostatic controllers.
Questions: Which metal will expand more when it is heated? What happens when it is cooled?
