A basic mercury thermometer is a precisely crafted piece of tube-shaped glass enveloping a mercury-filled reservoir connected to an extremely thin channel, called the capillary bore, that provides a chamber the mercury from the reservoir can expand into.The shorter, bulbous end of the tube containing the reservoir is called the bulb and the longer, narrower end with the bore is called the stem.
Dec 18, 2023 · In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale.
How do mercury thermometers work? Dating back to the 1800s, the oldest thermometers still used today are mercury in glass. This type of thermometer is a glass tube with a narrow hole down the center leading to a mercury-filled bulb.
Oct 19, 2023 · History. Mankind learned about thermodynamic temperature centuries after the first thermometer was invented. Therefore, initially, thermometers defined temperatures.The first thermometers, however, weren’t thermos or heat measurers, but thermo-scopes, devices that merely signaled whether the temperature was high or low.These devices weren’t calibrated to a standard scale; they would just ...
Mercury Thermometer. A mercury thermometer is a device used in scientific and clinical settings to measure temperature. It consists of a mercury-filled bulb connected to a capillary with a temperature scale, and its sensitivity is determined by the bulb volume and the coefficient of thermal expansion.
