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.
