It has two types of metal so when you put it on top of a candle it always curls the same way even if you flip it over........... I don't know what it's used for i have only seen it used once in a grade seven science class so that is all i know bout it.
A bimetallic strip is used in physics to show expansion of metals. Different metals expand in different amounts when exposed to heat. When you heat a bimetallic strip, one metal will expand more than the other so the strip will bend to one side.
A bimetalic strip is two different kinds of metals fused together. When you heat it up, the dissimilar stretch rates causes it to bend. It can drive a contact that turns a heating element on and off, thus operating as a thermostat.
Different metals have different coefficients of expansion. They expand and contract at different rates, depending on what they are made of.
If you take two dissimilar metal strips and glue, or weld, them together, as one changes size compared to the other, it will cause the combined strip to bend.
This is useful for temperature measurement.
You can either attach a pointer through gears and levers, to amplify the movement, or make it operate a switch for electrical control.
It is an experiment that demonstrates thermal expansion. Two metals with different thermal expansion coefficients are bonded together and when heated, one will expand more than the other, causing the strip to bend to one side. No matter which way you direct the flame, the metal which expands more will bend in the same direction. This is used as a thermometer because the more intense the heat, the bigger the curve.

what are avdantages and disavdantages of a strip thermometre
A bimetallic thermometer uses a bimetallic strip wrapped into a coil. This strip usually consists of either steel and copper or steel and brass. A bimetallic thermometer is a type of thermometer made with a couple metal strips. They have differing thermal expansions that are brazen together. Any distortion in this apparatus caused by variations in the temperature is used to measure the temperature.
copper capture the exact temperature of the body
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 out of steel and iron
A bimetallic strip is made from two different metals that expand at a different rates. Two strips of these metals are bonded together, and when the temperature changes, one side expands more than the other, forcing the bimetallic strip to curl (the longer side would be on the outside of the curl). So if one end is clamped, the other moves. This motion is used to turn the dial of the thermometer.
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.
