Why care must be taken when disposing of a mercury-in-glass thermometer?
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.
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 happens to the mercury in the thermometer when the air is cool?
In a mercury thermometer, the level of mercury falls as the temperature of the air around it cools.A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.
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.
Why water is not used in thermometer?
Well, Mercury can't freeze or evaporate at the temperature recorded on a standard thermometer. If water were used in a thermometer, we wouldn't be able to record any temperatures below its freezing point (0 degrees Celsius) or above its boiling point (100 degrees Celsius. Mercury has many unique properties. It is a liquid metal and as a metal it expands when heated. When the mercury is heated it rises in the thermometer. And markings on the glass indicate the temperature. Water does not do this. But now in this Digital World mercury has been loosing its importance just because everyone wants to use Digital Technology which provide fast and accurate reading and also safe in use, no doubt mercury provides an accurate reading of temperature but it is not fast and safe as compared to Digital Thermometer.

Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
Why is it that the clinical thermometer does not have temperatures less than 34 Celsius or more than 41 Celsius?
Because those limits will cover the temperature of most humans. 34oC is only 93.2oF and 41oC is 105.8oF. The 'normal' temperature for a healthy adult is 37oC or 98.4oF - which falls roughly half-way between the upper and lower limits of a clinical thermometer. Below 34C and above 41C one is in danger of death so help is needed immediately and there is no need in early diagnosis to know temperatures below or above that

What do you do before taking an axillary temperature?
Shake down the thermometer before using, if the reading on the thermometer is 94.0º F or above.
Is there air in a glass thermometer?
Yes, above the mercury or the other liquid.
Why would a 0C to 100C thermometer be useless to a doctor examining a patient?
It would not be accurate enough. The clinical thermometer works over a limited range and gives accurate more readings. It would be useful. The temperature of patients rarely drop below freezing and they rarely boil. It would be useless to measure the temperature of food though because food is often cooked above 100C.
Are there standards for thermometer deployment?
standards for thermometer deploymentAnswerYes. In a white louvred box (Stevenson Screen) with the sensors 1.1 metres above ground level.
Do rottweilers have markings above their eyes?
Yes they do, they have a small spot (Deep tan/Mahogony in colour) above each eye.
Why does the clinical thermometer has a short temperature range from 35 degree Celsius to 42 degree Celsius?
Because4 at below 35o Celsius you are dead and at above 42o Celsius you are also dead!! Somewhat kidding, but these temperature extremes are rarely seen in humans anyway, so why have a wider scale.
