What else can I help you with?
Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
What is the importance of a narrow tube in the clinical thermometer?
A narrow tube in a clinical thermometer allows for more precise measurement of body temperature by amplifying small changes in temperature. This leads to accurate readings, crucial for detecting even slight fluctuations in body temperature, which can indicate illness.
Why does a stem in clinical thermometer have a small cross section area?
The small cross section of a clinical thermometer is there to reduce the amount needed of the toxic mercury to as little as possible. Mercury is less used nowadays, as breakages were likely due to the violent shaking needed to 'reset' the thermometer.
Why should a clinical thermometer not be sterilize in boiling water?
Because clinical thermometer have a very small range. (20 to 45 degrees Celsius at most) and if placed in boiling water, the water being 100 degrees will cause damage to the thermometer.
What is a constant volume gas thermometer?
A constant volume gas thermometer is a thermometer that uses the variations of pressure in gas at different temperatures to measure the temperature. A liquid can then be put into tubes, and rather than measuring the distance of a small quantity, the distance between two parts of the curving tube are used to measure the temperature.
Why does a clinical thermometer have a small range of degrees?
Because living humans are homeotherms.
What is a clinical thermometer?
A clinical thermometer, this type of thermometer is sensitive to very small changes in temperature but is able to measure temperatures only within a few degrees of normal body temperature (thirty seven degrees celsius).

What is a constant-volume gas thermometer?
A constant volume gas thermometer is a thermometer that uses the variations of pressure in gas at different temperatures to measure the temperature. A liquid can then be put into tubes, and rather than measuring the distance of a small quantity, the distance between two parts of the curving tube are used to measure the temperature.

Why in a clinical thermometer the bulb is not quite full of mercury at room temperature?
In a clinical thermometer, the bulb is not completely full of mercury at room temperature to allow for the expansion of the mercury when it is heated. This design ensures that the mercury can rise freely in the narrow capillary tube without any obstruction, providing an accurate reading of the temperature. Additionally, the small air pocket in the bulb prevents the mercury from spilling and enables it to return to its original position after the thermometer is removed from the heat source.
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
As the temperature rises or falls the liquid in the reservoir (bulb) of the thermometer rises or falls ) the liquid expands (heats up) or contacts (cools off). The volume change is made visible in the capillary (tube) in the part of the thermometer with the scale. This is the only part of the thermometer into which the extra volume and expand.Increasing the volume of fluid or decreasing the diameter of the capillary makes the changes more apparent/
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.
