2 days ago · The bulb of a mercury-in-glass thermometer. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some liquid-in-glass thermometers, especially those used to measure high temperatures.
4 days ago · Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
Jul 12, 2024 · The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature and should be the same on both scales. If the two readings are not the same, then the instrument scales are not correctly positioned or the instrument is damaged.
3 days ago · A mercury thermometer is a thermometer that uses mercury to determine the temperature. It's filled with liquid mercury and an upward-pointing quill inside a glass tube. The density of the liquid metal causes it to collect at the tube's higher end when the mercury column in the tube is inverted.
5 days ago · Using a Mercury Thermometer? Here’s What to do if it Breaks. The first thing to remember if you break a mercury thermometer is that the silvery substance contained within those glass tubes has the potential to be highly toxic.
Jul 11, 2024 · Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature. It is used in older thermometers, fluorescent light bulbs and some electrical switches.
Jul 12, 2024 · Mercury does not wet glass or cling to it, and this property, coupled with its rapid and uniform volume expansion throughout its liquid range, made it useful in thermometers. (Mercury thermometers were supplanted by more accurate electronic digital thermometers in the early 21st century.)
