Why are two different metals used to produce movement in bimetal elements?
Two different metals are used in bimetal elements because they have different coefficients of thermal expansion. When heated or cooled, these metals expand or contract at different rates, causing the bimetal strip to bend. This bending motion is used for various applications such as in thermostats or circuit breakers.
Can one produce energy with a bi metal strip when heated?
Yes, a bimetal strip can be used to produce energy when heated by converting the thermal energy into mechanical energy. When the bimetal strip bends due to differential expansion of its constituent metals, this mechanical energy can be harnessed to perform work or generate electricity using a suitable mechanism like a generator.
Iron has linear expansivity of 0.000012k brass has a linear expansivity of 0.000019k . draw diagrams to show what will happen to a bimetal strip made from ironand brass if it is heated or cooled.?
When the bimetal strip is heated, the brass side will expand more than the iron side due to its higher expansivity, causing the strip to bend towards the brass side. When cooled, the brass side will contract more than the iron side, causing the strip to bend towards the iron side. This bending can be used in devices like thermostats to control temperature.
Who invented the bimetal thermometer?
The bimetal thermometer was invented by Johan August Arfwedson in 1860.
What is the thermometric substance of bimetallic thermometer?
Ah, the thermometric substance of a bimetallic thermometer is actually the two different metals that make up the strip inside. These metals expand at different rates when heated, causing the strip to bend. It's like a little dance they do together, showing us the temperature changes in a beautiful and simple way. Just imagine those metals dancing in harmony, creating a lovely symphony of temperature readings for us to enjoy.

What does a bimetal thermometer do?
A bimetal thermometer is two strips of different metals that have been stuck together. because the two metals will have differing rates of expansion under heat, the strip will bend towards one side. if the thermometer is colder than standard temperature, the strip will bend towards the side with a higher expansion rate, and if it is hotter, than it will bend towards the metal with the lower expansion rate. Because the expansion is a fixed property of a metal, a bimetal thermometer will have a relative accuracy because of them.
Does the bimetallic strip bend when heated?
yes
What is a bimetic strip?
A bi-metal strip is a bimetallic strip that is used to convert temperature changes into mechanical movement. It consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
Can one produce energy with a bi metal strip when heated?
Yes, a bimetal strip can be used to produce energy when heated by converting the thermal energy into mechanical energy. When the bimetal strip bends due to differential expansion of its constituent metals, this mechanical energy can be harnessed to perform work or generate electricity using a suitable mechanism like a generator.
A bimetal hermetic motor internal overload is?
A bimetal hermetic motor internal overload is a protective device used in hermetic motors to prevent overheating and potential damage. It consists of two different metals that expand at different rates when heated, causing the bimetallic strip to bend and break the electrical circuit. This interruption helps safeguard the motor from excessive current and heat, ensuring its longevity and reliable operation. Once the motor cools down, the overload can reset, allowing the motor to operate again.

What happens when cans are in a heated area?
The cans mely or bend!:^)

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 is the part of the mantle that can bend plastic?
Heat transfer by the movement of a heated fluid is called _________?
