Describe bimetal strips and how they work.
What will be an ideal response?
The bimetal strip is made by bonding two dissimilar types of metal together. Because these two metals are not alike, they have different expansion rates. This causes the strip to bend or warp when heated. A bimetal strip is often formed into a spiral shape. The spiral permits a longer bimetal strip to be used in a small space. A long bimetal strip is desirable because it exhibits a greater amount of movement with a change of temperature.
