What happens when bimetallic strip is heated?
The bimetallic strip bends.
What is the principel of bimetallic strip?
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.
What happens to bimetallic strip when it is heated and cooled?
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.
What is two strips of different metals welded together causing the strip to bend when heated?
That's a "bi-metal" or "bi-metallic" strip.
What is principel of biametallic strip?

Why does a bimetallic strip bend when heated?
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.
Which direction does a bimetallic strip bend when cooled?
It depends how it has been constructed
What changes takes place when bimetallic strip is heated?
actually what happen is that the strip is curved to the outside
When a bimetallic strip is heated it bends toward the metal with the thermal expansion?
... smaller ...
What uses bimetallic strip?
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.
Which direction does bimetallic strip bend toward higher or lower coefficient of expansion?
Lower
