I1-13. Thermal Expansion - Bimetal Strip
Purpose
To demonstrate differential thermal expansion.
Equipment
Bimetal strip with burner.

Description
Strips of invar steel and brass are welded together to form a bimetal strip. Because their coefficients of thermal expansion are different, heating the bimetal strip over a burner results in bending, as illustrated. This type of material is used in some types of thermostatic controllers.
