Why is the bore on a clinical thermometer narrower directly above the bulb?
The bore of a clinical thermometer is narrower directly above the bulb to slow down the expansion of mercury and provide a more accurate reading. This design helps to prevent sudden changes in temperature from affecting the reading, making the thermometer more precise.
What is the function of the bore in a thermometer?
The bore in a thermometer is the narrow tube where the liquid (mercury or alcohol) expands and contracts with temperature changes. This expansion and contraction of the liquid in the bore allows the thermometer to measure and display the temperature accurately.
Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
The narrow capillary bore allows for more precise measurement of temperature changes because the mercury expands and contracts more readily in the smaller tube. This enables the thermometer to detect even small variations in temperature accurately.
How does length and bore affect sensitivity of mercury thermometer?
The sensitivity of a mercury thermometer is affected by its length and bore. A longer thermometer will respond more slowly to temperature changes due to the increased mercury column length, while a wider bore allows for more mercury movement and can increase sensitivity to small temperature changes.
What is the advantage of having the liquid thermometer move up a narrow bore?
Having the liquid thermometer move up a narrow bore helps to magnify even small changes in temperature, making the measurements more accurate. It also allows for a greater range of temperatures to be measured within a smaller physical space. Additionally, the narrow bore provides a consistent and uniform environment for the liquid to expand or contract in response to temperature changes.

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

Why is a bore of thermometer so narrow?
The bore of a thermometer is narrow to ensure a quick and accurate response to temperature changes, as the narrow bore reduces the amount of mercury or other liquid needed to fill it. A narrow bore also allows for more precise temperature readings, especially when measuring small temperature differences.
The capillary tubing has a uniform bore in a mercury thermometer?
yes ! to insure linearity
Why the lab thermometer has very fine bore?
The fine bore in a lab thermometer allows for a quicker response time to temperature changes due to the reduced volume of liquid inside. This allows for more precise and accurate temperature readings in a laboratory setting. The fine bore also reduces the parallax error when reading the temperature scale.
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 is a bore on a shotgun?
Bore is the number of lead spheres the diameter of the barrel it would take to equal one pound. Ergo, the larger the bore, the smaller the barrel.
How should you do to increase the accuracy of the thermometer?
using a thin capillary bore using a thick glass stem
