Mercury-in-glass thermometer for measurement of room temperature. The mercury-in-glass or mercury thermometer is a thermometer that uses the thermal expansion and contraction of liquid mercury to indicate the temperature.
18 Dis 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. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
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.
30 Mei 2015 · 581. 164K views 8 years ago. Daniel Fahrenheit built several types of thermometers, but his Stuff of Genius wasn't restricted to a few temperature measuring devices. Tune in and learn how Daniel...
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.
30 Apr 2024 · Mercury thermometers offer precision due to mercury’s unique properties, require regular maintenance for accuracy, and have alternatives like digital and bimetal thermometers for a range of temperatures.
19 Okt 2023 · The main reason mercury is used in thermometers is because it has a higher coefficient of expansion than water. This means that changes in its volume with temperature are more noticeable. Additionally, mercury has a boiling point of 356.7 degrees Celsius, which is much higher than alcohol’s boiling point of 78.37 degrees Celsius.
11 Jan 2023 · Once a staple in most medicine cabinets, mercury thermometers use mercury encased in glass to measure body temperature. Mercury thermometers are no longer recommended because they can break and allow mercury — which is toxic — to escape.
17 Jun 2024 · With the growing awareness of mercury exposure hazards, the shift towards mercury free thermometers in settings like homes, hospitals, and laboratories is becoming more prominent. These safer alternatives offer reliable and accurate temperature measurement while eliminating the risk of mercury exposure.
25 Apr 2017 · In a thermometer, a glass bulb attached to a glass capillary tube is filled with mercury. The rest of the tube may be a vacuum, or it may be filled with nitrogen. As the mercury heats up, it rises in the tube, and as it cools, it retracts back into the bulb.
