What shape can be said to be 'helical'?
When one uses the term "helical", one is often referring to the shape of a helix or spiral. An object with a spiral or helical shape, is one that has a shape or form similar to the helix.
Cellulose molecules have what shape?
helical (spiraling)
What should the temperature reading be for a bimetallic thermometer when calibrating in an ice water bath?
When calibrating any kind of thermometer in an ice water bath, the temperature should be 0o C or 32o F.
Who discovered that the sugar phosphate backbone of DNA lies on the outside of the molecule and has a helical shape?
James Watson and Francis Crick, 1953
What is the shape of DNA?
Though shaped like a spiral ladder it consists of two helical polymers if it was to be unwound. On the outside of the ladder is phosphate and sugars, and in the middle are the bases associated in pairs, one base coming from one helical strand and one from the opposite helical strand.
What is helical bimetallic strip?
A helical bimetallic strip is two strips of metal with differing boiling points that have been fused together, spiraling upwards around a central object. When heat is applied to the bimetallic strip, the different chemical properties in each metal strip will cause them to expand, forcing the helical strip to expand upwards.
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.
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

Bimetallic thermometer is used for what?
Its simple . to measure the temperature
WHAT IS a bimetallic thermometer used for?

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.
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
