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.?

It is easier to open because the hot water is like fire. So the cap is not strong to hold the hot water. becouse the top expands befour the heat reaches the bottle which makes it a looser fit

What is the bimetal mechanical thermometer?
The bimetal mechanical thermometer uses one end of a bimetallic coil connected to the housing of the device and the other end drives an indicating needle. The bimetal mechanical thermometer is often used in things like refrigerators, air conditioners and heat control.
What is a bimetallic strip used in?
Bimetal strips can be used for thermocouples. The two metals will have different expansion rates and the difference will generate a small amount of electricity. The electricity generated can be collated to a given temperature. Your mom
How does a dial thermometer function?
Most dial thermometers use a bimetal spring to drive the pointer on the the thermometer face. Two metals are laminated together and wound to form the spring. One metal expands (or contracts) more rapidly than the other due to temperature changes. As the spring's shape changes the pointer moves accordingly. Another type of dial thermometer uses temperature-sensitive gas in a sealed tube to drive the point.
Why does a bimetallic strip consist of 2 metals?
A bimetallic strip consist of two metals in order to detect rapid changes in temperature. Used in conjunction with some fire alarm systems, bimetal strips will detect rapid changes in temperature using the differences in expansion rate of the two metals. As one half of the strip expands more rapidly than the other, it will cause the strip to bow or bend causing it to touch a nearby contact sensor thus activating the ' rate of rise' temperature sensor, which may or may not be tied into an alarm system.

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.
What is the Functions of a choke?
It's bimetal so opens when warm releasing choke which richens mixture until warm enough to run without it.

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.
A bimetal strip has two metals of different?
It depends on the properties you want. A good chart is provided by EMS at http://www.engineeredmaterialssolutions.com/6-clad_solutions.html that lists applications and the types of bonded material to use.
