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.

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?
A clinical thermometer is a device used to measure body temperature. It typically consists of a long, narrow, sealed glass tube containing a liquid such as mercury or alcohol that expands and contracts with changes in temperature. The thermometer has a temperature scale marked along its length for easy reading of the temperature.
How does a thermometer indicate the temperature of an object?
A thermometer measures temperature using a temperature-sensitive material, such as mercury or alcohol. As the material heats up or cools down, it expands or contracts, causing the level to rise or fall on a scale marked with temperature values. This movement of the material provides a reading that represents the temperature of the object being measured.
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.

What is Mercury's length of year on Mercury?
It is approx 88 days.
When the temperature increases the level of mercury in the thermometre rises why does this occur?
This occurs because mercury expands when heated, causing it to rise in the thermometer. As the temperature increases, the molecules in the mercury move more rapidly, leading to an increase in volume and a rise in the mercury level within the thermometer.
