"A bimetallic strip is made of two different metals stacked in a thin strip. Because different metals expand at different rates, one of the metals expands more than the other when the strip gets hot. This makes the strip coil and uncoil in response to changes in temperature=As the room temperature drops below the desired level, the bimetallic strip coils more tightly, and the glass tube tilts. A drop of Mercury closes an electric circuit that turns the heater on. As the room temperature rises above the desired level, the bimetallic strip uncoils slightly, becoming larger. The drop of mercury rolls back in the tube, opening the electric circuit and the heater turns off."==Quote from Holt, Rinehart, and Winston Physical Science Textbook=
What else can I help you with?
Why dies a bimetallic strip when it is heated?
A bimetallic strip bends when heated because the two metals it is made of have different coefficients of thermal expansion. As the strip is heated, one metal expands more than the other, causing the strip to curve.
Which direction does a bimetallic strip bend when cooled?
A bimetallic strip bends towards the side of the metal with higher coefficient of thermal expansion when cooled. This is because the metal with the higher coefficient of thermal expansion contracts more when cooled, causing the bimetallic strip to curve towards that side.
What is a bimetallic strip and where can it be used?
A bimetallic strip is made of two different metals bonded together, which have different coefficients of thermal expansion. This causes the strip to bend when heated or cooled. Bimetallic strips are often used in thermostats, temperature switches, and circuit breakers to control temperature-sensitive mechanisms.
Which two metals are used in a bimetallic strip?
The two metals commonly used in a bimetallic strip are steel and copper. These metals have different coefficients of thermal expansion, causing the strip to bend when heated or cooled due to the uneven expansion and contraction of the metals.
What way does a bimetallic strip bend with iron and brass?
When heated, a bimetallic strip made of iron and brass will bend towards the brass side due to the different coefficients of thermal expansion of the two metals. This is because brass expands more than iron when heated, causing the strip to curve towards the side with greater expansion.
Why is a bimetallic strip curve when it is heated or cooled?
Because the two metals have different coefficient of linear expansion
Why dies a bimetallic strip when it is heated?
A bimetallic strip bends when heated because the two metals it is made of have different coefficients of thermal expansion. As the strip is heated, one metal expands more than the other, causing the strip to curve.

A bimetallic strip bends towards the side of the metal with higher coefficient of thermal expansion when cooled. This is because the metal with the higher coefficient of thermal expansion contracts more when cooled, causing the bimetallic strip to curve towards that side.
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.

Does the bimetallic strip bend when heated?
yes
What happens to bimetallic strip when it is heated and cooled?
When a bimetallic strip is heated, the two metals expand at different rates causing the strip to bend towards the metal with the lower coefficient of thermal expansion. Conversely, when the strip is cooled, it bends towards the metal with the higher coefficient of thermal expansion. This bending action can be harnessed for applications like thermostats and temperature-sensitive switches.

When heated, a bimetallic strip made of iron and brass will bend towards the brass side due to the different coefficients of thermal expansion of the two metals. This is because brass expands more than iron when heated, causing the strip to curve towards the side with greater expansion.
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.
Why are two different metals used to make a bimetallic strip?
Two different metals are used to make a bimetallic strip because each metal expands and contracts at different rates when heated or cooled. This difference in thermal expansion causes the strip to bend, making it useful in applications such as thermostats and thermal switches.
