A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.

What is a dual probe thermometer?
this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
What is the difference between a chocolate thermometer and a regular thermometer?
A chocolate thermometer and a regular thermometer differ from each other by its size and sturdiness. The chocolate thermometer are much bigger than the regular thermometer so that it can withstand the extreme heat. The normal thermometer can withstand less heat than the other one.
How can you use the words inquiry and thermometer in one sentence?
I did not understand the nurse's inquiry as to what I had done with the thermometer. Will an inquiry be necessary to find that thermometer? A silent thermometer has no inquiry.
Function of thermometer?
The function of a thermometer is to measure temperature.
Which thermometer shows degrees Celsius?
the Celsius thermometer
Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
To increase the sensitivity of the thermometer, that is, for the thermometer to respond quickly to small changes in temperature.
How do you increase the range of a thermometer?
If you're the one designing the thermometer, you could make it longer or make the bore wider. If you've got an existing thermometer, there's not much you can do.
The capillary tubing has a uniform bore in a mercury thermometer?
yes ! to insure linearity
Why are the thermometers called liquid in glass thermometers?
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
How should you do to increase the accuracy of the thermometer?
using a thin capillary bore using a thick glass stem
What is difference between a clinical and a laboratory thermometer?
A lab thermometer normally is very long and has a wide range of measurement with uniform degrees spread out over the distance and has a mark showing how far into the measured substance it go to get accurate measurements.A clinical thermometer has a larger bore at the bottom where the contents can expand without measurement occuring then a tiny bore where the degrees are spread out at the body temperature. Thus at room temp, all the liquid is down in the big area and only as it gets up to 95 degree or so is the liquid expanded in the reading area. This allows the thermometer to be physically short and easy to handle while having wide degrees to be easy to read. There is also a trap so that the column separates leaving liquid in the tiny bore to read instead of dropping quickly on removal. The liquid has to shaken out of the tiny bore back into the big one.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
Why does a mercury-in glass thermometer first drop slightly when placed in boiling water?
When placed in boiling water, the materials comprising the thermometer respond in the order in which the heat penetrates them. As the heat first permeates the glass cylinder, the cylinder expands, enlarging the bore. For the moment until the mercury is also heated, the constant volume of mercury fills the expanded bore to a slightly lower depth. When the heat reaches the mercury and it also expands, its volume to increase, and the liquid depth rises in the bore.
What are three differences between clinical and laboratory thermometers?
A lab thermometer normally is very long and has a wide range of measurement with uniform degrees spread out over the distance and has a mark showing how far into the measured substance it go to get accurate measurements. A clinical thermometer has a larger bore at the bottom where the contents can expand without measurement occuring then a tiny bore where the degrees are spread out at the body temperature. Thus at room temp, all the liquid is down in the big area and only as it gets up to 95 degree or so is the liquid expanded in the reading area.

There is also a trap so that the column separates leaving liquid in the tiny bore to read instead of dropping quickly on removal. The liquid has to shaken out of the tiny bore back into the big one.
How does the size of capillary bore of a thermometer affect its accuracy?
As the temperature rises, the mercury expands into a narrow bore, because the volume of the mercury increases. If the bore is very narrow then the extra volume has to go a longer way up the bore to accomodate that volume, so it is more sensitive to small changes of temperature. And it is easier to spot small changes of temperature, and read them from the scale more accurately. But if the scale isn't marked accurately in the first place you are no better off.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
What is the working and construction of thermometer?
WORKING: Place the bulb of the thermometer filled with mercury in a vessel ov small pieces of ice the mercury will arise in the tube and will come to rest at a certain point.this point shows the melting point of ice. CONSTRUCTION:A thermometer consists of a glass bulb filled with mercury.A cappilary tube arises from this bulb.Due to the narrow bore of the tube a small change in the volume of the mercury becomes significiantly visible.
