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 else can I help you with?
Why clinical thermometer is jerked before using it again?
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
Can you give a technical description of the clinical thermometer?
Definition:It is an instrument used to measure body temperature.Diagram:Description:It is a small glass thermometer designed for clinical use in humans or animals. Designed with a narrowing small glass above the bulb so that the mercury column stays in position when the instrument is removed from the body. It is carefully calibrated at the time of manufacturing. Now a days mercury thermometer not used because it can break, spilling mercury posing a risk of human or animal health. they can be inserted in the month, armpit, anus or even attached to the forehead depending on the design.
How does a thermometer indicate the temperature of an object?
The heat of the object heats the metal tip and heats the liquid inside (usually mercury) until it expands, thereby filling the thermometer. Various tests are performed to determine at what length is what temperature.
What is the sensitivity of an instrument?
The sensitivity of an instrument is the smallest amount it can measure, of whatever it's built to measure.Anything smaller than the sensitivity of the instrument, and the instrument doesn't even notice it.For example, a laboratory scale can measure the weight of a hair, but a truck scale can't. We say that thelaboratory scale's sensitivity is much smaller (or lower) than the truck scale's sensitivity.
What should bethe shape of an ideal thermometer?
An ideal thermometer usually has a thin glass tube with a uniform bore, capped at one end with a bulb containing a temperature-sensitive liquid like mercury or alcohol. The tube should have uniform markings along its length for accurate temperature reading. The thin design allows the liquid to expand and contract easily as the temperature changes.
How do you increase sensitivity of mercury in glass thermometer?
Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh
What is the temperature of the mercury when the length of the mercury thread is 8cm?
The length of a mercury thread in a thermometer is not directly related to the temperature of the mercury. The temperature is denoted by the level that the mercury rises to in the calibrated tube. The length of the mercury thread only indicates the volume of mercury present.
Who invented the Mercury thermameter?
The mercury thermometer was invented by German physicist Daniel Gabriel Fahrenheit in 1714. He introduced the use of mercury as a temperature indicator in a sealed glass tube, which allowed for more accurate temperature measurements compared to previous methods.
Which thermometer is best for baby?
A digital thermometer is less 'intrusive' - as you don't need to hold it in place for any length of time (as you would with a mercury thermometer). Digital ones give you an almost instant reading.
What is the formula between length of mercury level and temperature in degree celsius?
There is none. In the case of a thermometer, it will depend on the relative dimensions of the bulb and the capillary tube.
What is the length of a fever thermometer?
Centimeter
Why is the stem of a thermometer made up of glass?
Because Mercury expands in heat, it is more accurate than other elements used in thermometers.

When the temperature increases the level of mercury in the thermometre rises why does this occur?
When the temperature increases, the molecules in the mercury inside the thermometer gain kinetic energy and move more rapidly. This increased movement causes the mercury to expand, leading to a rise in its level within the narrow tube of the thermometer. The expansion of the mercury is a result of its thermal expansion coefficient, which is a measure of how much a material expands or contracts with changes in temperature.
What is Mercury's length of year on Mercury?
It is approx 88 days.
If the thermometer is 25 cm long what is the length in millimeters?
To convert centimeters to millimeters, you need to multiply by 10 since there are 10 millimeters in 1 centimeter. Therefore, if the thermometer is 25 cm long, you would multiply 25 by 10 to get the length in millimeters. The length of the thermometer in millimeters would be 250 mm.
