In scientific settings, precise temperature readings necessitate the use of specialised equipment, such as a laboratory thermometer.
Either a small or large portion of it can be submerged into the material being measured. The silver bulb at the end of a lengthy stem is the telltale sign that a thermometer is meant for use in a laboratory.
If the bulb is silver in colour, then mercury is most likely present. When the temperature rises, the mercury in the thermometer expands and the reading rises, while when the temperature falls, the mercury contracts and the reading falls.
These days, most people choose digital, alcohol-filled, or organic-based thermometers to the traditional mercury-in-glass models.
Hence, Body Temperature is Not Measured With Laboratory Thermometers.
Clinical thermometers are the gold standard for taking a person’s temperature. There is a kink in clinical thermometers that keeps the mercury from re-entering the bulb after being removed from the patient’s mouth. Clinical thermometers have a temperature range of 35°C to 42°C.
Because of its expansion at higher temperatures and contraction at lower temperatures, mercury is commonly employed in thermometers.

As Temperatures Rise, The Mercury in a Thermometer’s Column will Fall.
A thermometer is a tool for taking temperature readings. If you want to know the temperature, just look at how high up in the air the mercury column is.
In the event that the marks on a thermometer’s scale are erased, we can redraw them using ice’s melting point (which is 0 degrees Celsius) and water’s boiling point (which is 100 degrees Celsius) as our starting and ending points, respectively. Once the maximum and minimum points are found, the distance in between them is divided into 100 equal segments.
