Its a liquid at room temperature and it has a high rate of thermal expansion and contraction(changes volume with temperature).
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.

Well i'm not that old but i know a few:1)The thermometer will be of two types; a) Clinical Thermometer b) Laboratory Thermometer;a) The Clinical Thermometer: used to measure the temperature of the human body, at home, clinics and hospitals.b) The Laboratory Thermometer: used to measure the temperature in school and other laboratories for scientific research.Precautions:Wash the thermometer before and after use with an antiseptic solution, and handle it with care.See that the mercury levels are below the kink and don't hold the thermometer near its bulb.While noting down the reading in the thermometer, place the mercury level along the eye sight.Do not place the Clinical thermometer in a hot flame or in the hot sun.Note:The Clinical Thermometer should go above 108*F (42*C) and below 94*F (35*C) otherwise it might blow off the top and leak. Therefore, a Clinical Thermometer is used to measure the body temperature.
Clinical thermometers are made to be used in a hospital to accurately determine body temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park." A clinical thermometer may have mercury but lab thermometers usually have alcohol .
A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature. A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature.
A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.

Mercury can be found in the labarotry or in the clinical thermometer.
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
kink
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
mercury
Mercury is used in clinical thermometers.
Mercury expand more easily.so it need large space
- a thermometer with mercury - a thermometer with thermoresistance
We cannot use a clinical thermometer to measure temperature of a candle flame because then the mercury will expand too much and the thermometer will explode.
