because the strip has to go inside the thermometer so it needs to metals just to make it go inside the thermometer :) #loving my life :)
A bimetallic strip is made up of two metals (the prefix "bi-" means "two"). The two metals have different coefficients of thermal expansion.
Thermostats,.
A bimetallic strip is made out of copper and steel.
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.
it consists of strips madeof two different metals with different coefficient of expansion.use as fire alarm etc...

A bimetallic bar has two different metals bound together. Different metals have different coefficients of thermal expansion. As the temperature changes, the metals will expand or contract different amounts - consequently the bar will curve on the side of the one that expands the least or contracts the most (depending on whether it is warming up or cooling down).

Because the two metals have different coefficient of linear expansion
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.
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.

A bimetallic strip is a strip with two metals bonded together. It can be found in thermostats
A strip of two different meals joined together is called a bimetallic strip.
Rates of physical expansion, over the same temperature change.
The two metals chosen for the bimetallic strip have different modulii of thermal expansion, The bimetallic strip bends as the temperature changes and so the strip can be used to activate relays or other electronic switches and so work as a thermostat.
