Basically you have two different kinds of metal with different coefficents of expansion put together. As they expand it creates a curving effect because one is expanding more than the other. This drives the needle and gives the indication. http://en.wikipedia.org/wiki/Bi-metallic_strip

∙ 13y agoThis thermometer consists of a bar made up or two strips, each of a different metal. The metals, such as brass and iron, expand different amounts when heated. The bar will curve when heated and straighten again when cooled.

What is the advantage between a bimetallic thermometer and an ordinary thermometer?
If you mean by an "ordinary" thermometer, a mercury thermometer, the bimetallic type can measure a far greater range of temperature (mercury freezes at -38oC and boils at 356oC making it useless in the polar regions or for measuring high temperatures).Bimetallic thermometers are also more robust; mercury thermometers are usually made from glass and are fragile.
Is sharpening a pencil a physical property?
Sharpness is a physical property. Sharpening is not a property, it is an action designed to produce a property.
Is luster a typical physical property of metals?
Luster is a physical property of crystals.
A physical property is a characteristic of a substance is one that?
Density is a physical property; physical properties are measurable.
Characteristic of a substance that can be measured or observed without changing the identity of the material?
I believe that you are referring to physical properties. They are observed without changing composition of the substance. Physical properties are more obvious things like colour, shape, etc.
What is a bimetallic thermometer?
A bimetallic thermometer uses a bimetallic strip wrapped into a coil. This strip usually consists of either steel and copper or steel and brass. A bimetallic thermometer is a type of thermometer made with a couple metal strips. They have differing thermal expansions that are brazen together. Any distortion in this apparatus caused by variations in the temperature is used to measure the temperature.
Who invented the bimetallic thermometer?
Jhon harison

What is the use of a bimetallic thermometer?
A bimetallic element is used in order to react it from various temperature that will indicated the temperature of an object or body.
What is a Bimetallic stemmed thermometer?
basically, a Bimetallic Stemmed thermometer is a thermometer that is used when cooking meats- like turkey (well turkey is poultry, but that is not the point) . They have a long stem that you poke into the meat and there is a dial on the top that tells you how hot the inside of the meat is.
What are the advantages and disadvantages of a bimetallic strip thermometer?
what are avdantages and disavdantages of a strip thermometre
What are the function of Bimetallic thermometer?
A bimetallic thermometer has a coil of metal strips in it. The metal strips are made of two different materials that expand/contract at different rates. Because they're connected together at one end, when the metals warm up or cool down, the coil changes shape. You use a bimetallic thermometer when you want an electrical circuit to close due to a change of temperature.
Why the copper use in bimetallic strip thermometer?
copper capture the exact temperature of the body
What is the calibration nut on a bimetallic stemmed thermometer used for?
To keep it accurate.
