The Bi-metallic Strip works on simple thermal dynamics. 2 different metals are brazed together, and when heated or cooled, the metals expand or shrink at different rates, causing it to move in one direction or the other. they are used in thermostats in kettles and irons and have other useful applications too.

That's a "bi-metal" or "bi-metallic" strip.
A bimetallic strip is made out of steel and iron
A bimetallic strip bends when heated because it is composed of two different types of metal. The different metals form the two sides of the strip expand and contract at different rates when subjected to a temperature change. When heating a bimetallic strip, one side of the metals expands faster than the other, making it longer. Because it is bonded to the other metal, it cannot expand in a straight line. 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.
A bimetallic strip is a strip with two metals bonded together. It can be found in thermostats
The bimetallic strip bends.
yes
actually what happen is that the strip is curved to the outside

A bimetallic strip is made from two combined metal strips that have different rates of expansion when heated. This causes the strip to bend and so close or open an electrical contact switch.
Appliances like electric iron, which need a cut off from the electric current from time to time as the appliance is heated adequately, use bimetallic strip for this.
The two metals have different expansion rates when the strip is heated. This means that one of the metals will expand more than the other, causing the strip to bend.

Because the two metals have different coefficient of linear expansion
