the thermometer is shaken before it is used because it is
If the clinical thermometer is a mercury based thermometer, it needs to be shaken down prior to each use. This is because there is a pinch point between the mercury reservoir bulb and the capillary tube, to ensure that the mercury does not shrink back into the bulb after the temperature has been taken. The mercury has therefore to be shaken back into the bulb before another measurement can be made. One should note that in many countries use of mercury based clinical thermometers is now discouraged (because mercury is toxic) and electronic thermometers are used in stead - these do not need shaking.
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
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.
What kind of thermometer you use to measure the body temperature
human body temperature,to measure it
Measurement of human body temperature.
No.
A clinical thermometer is a special type of thermometer designed for measuring human body temperature accurately. It has a more narrow range compared to other thermometers, typically between 95°F to 110°F, which allows for greater precision in detecting changes in body temperature. Additionally, clinical thermometers are usually made of non-toxic materials for safe use in the mouth, underarm, or rectum.
no please there's mercury which will just poison you
No, a clinical thermometer is not suitable for measuring the temperature of a candle flame. Candle flames burn at temperatures much higher than the range typically measured by a clinical thermometer. To measure the temperature of a candle flame, a specialized high-temperature thermometer or pyrometer would be more appropriate.
No, a clinical thermometer is not suitable for measuring the temperature of hot tea as it is designed for measuring human body temperature. The high temperature of the hot tea could damage the clinical thermometer or give inaccurate readings. It is better to use a food thermometer designed for measuring the temperature of liquids.
