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.
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. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
Dec 15, 2020 · Mercury thermometers provide accurate temperature readings and can be used orally, rectally, or under the arm. They don’t require batteries. Drawbacks
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.
Oct 19, 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.
May 30, 2015 · 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 Fahrenheit invented the...
A broken mercury-containing thermometer can be toxic if the vapors are inhaled. The risk of poisoning from touching or swallowing mercury from a broken thermometer is low if appropriate clean-up measures are taken.
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.
Jan 11, 2023 · Mercury thermometers are no longer recommended because they can break and allow mercury — which is toxic — to escape. If you have a mercury thermometer, don't throw it in the trash. Contact your local trash collection program to see if there's a hazardous waste collection site in your area.
Jun 27, 2018 · The main parts of a mercury thermometer are the capillary, the bulb, the scale, and the expansion chamber. Spherical Bulb. The bulb is the lowest part of the thermometer, which has a spherical shape. This section of the thermometer acts as a reservoir to hold mercury -- a silvery colored, heavy metal on the periodic table of elements.
