The two different metals welded together to make the strip have unequal rates of expansion when heated. The metal that expands furthest will force the lesser expanding metal to curve over and either make or break an electrical connection.
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.
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.
This phenomenon is known as bimetallic strip. When the two metals expand at different rates, due to their different coefficients of thermal expansion, the strip bends as one side elongates more than the other when heated.
A bimetallic strip is composed of two different metals with different coefficients of thermal expansion. When heated, the two metals expand at different rates, causing the strip to bend. The side with higher expansion will curve outward due to the lengthening of that metal compared to the other side.
When the two metals are heated or cooled through the same change in temperature, one of them expands or contracts more than the other one does. That's why, when they're glued back-to-back, the combined strip develops a curve in it when it's heated. It curves away from the one that expands more, and toward the one that expands less.

Because the two metals have different coefficient of linear expansion
A biometallic thermometer measures temperature. It uses a differential thermal expansion of metals that are bonded together into a strip. Another name for these thermometers is differential thermometer.
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.
The bimetallic strip bends.
The curve showing the relationship between temperature and time for a given amount of liquid heated at a constant rate is called a "heating curve." This curve is mapped out on a graph.
yes
actually what happen is that the strip is curved to the outside
It is a heating curve. It shows the temperature changes over time as a substance is heated continuously at a constant rate, highlighting phase changes and plateaus in temperature where energy is absorbed to overcome intermolecular forces.
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.
