A bimetallic strip is made of two different metals with different coefficients of thermal expansion. When heated, one metal expands more than the other, causing the strip to curve due to the unequal expansion. This phenomenon is used in devices like thermostats to actuate a switch at a specific temperature.

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.
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 the bimetallic strip bent with the heat?
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.
What is the different about the two kinds of metal on the bimetallic strip of a thermostat coil?
A bimetallic strip in a thermostat coil typically consists of two different metals bonded together. The metals have different coefficients of thermal expansion, meaning they expand and contract by different amounts when heated or cooled. This temperature-dependent size difference causes the strip to bend, which is used to control the opening and closing of the thermostat.
What is two strips of different metals welded together causing the strip to bend when heated?
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.
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.
Why is a bimetallic strip curve when it is heated or cooled?
Because the two metals have different coefficient of linear expansion
What is the advantage of bimetal thermometer?
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.
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.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
A curve showing the relationship between temperature and time for a given amount of liquid heated a constant rate is a what curve?
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.
Does the bimetallic strip bend when heated?
yes
What changes takes place when bimetallic strip is heated?
actually what happen is that the strip is curved to the outside
What is a curve showing the relationship between temperature and time for a given amount of liquid heated at a constant rate?
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.
Why the bimetallic strip bent with the heat?
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.
Why bimetallic strip bend in curve instead of showing linear expansion on heating?
If one metal expands or contracts at a different rate than the other, and they are bonded together, as they are in a bimetallic strip, a curve is inevitable - it physically has to happen, if you think about it.
