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 happens to a hot bimetallic strip when it is cooled to room temperature?
It Melts:P.
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.
How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used as a thermometer or thermostat. The two metals expand at different rates which will make it bend. You can use this to find the temperature of an oven. When the temperature of the oven increases, the strip will curve and break the electrical contact which make the oven cool down. When the oven cools the bimetallic strip will become straight again and the electrical contact will be remade and the oven will begin to reheat again.
What is the role of the bimetallic strip and how it works in relationship to expansion of metals?
When heat is applied to the end, one of the metals will expand faster than the other and the coil can operate a switch or valve just as the thermocouple does.
Contains a piece of metal that bends when its hot?
A thermostat is the most common item containing a bimetallic strip.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
What happens to a hot bimetallic strip when it is cooled to room temperature?
It Melts:P.
Why is a bimetallic strip curve when it is heated or cooled?
Because the two metals have different coefficient of linear expansion
Does the bimetallic strip bend when heated?
yes
Which direction does a bimetallic strip bend when cooled?
It depends how it has been constructed
How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
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 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 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.
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.
How does the bimetallic strip function when heated?
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.
