The problem with a mercury thermometer is that the device can break, spilling mercury and posing a risk of human or animal health. Such thermometers can also be difficult to use, as they need to be held in place for several minutes, and they need to be swung to reset, as the ...
Used in conjunction with a thermometer, this device can help make general weather predictions. While weather is very complex, storms more or less follow certain patterns of high and low pressure systems. In simplified terms, a rising barometer means wind, frost, or clear skies, while a falling...

As with a mercury-in-glass thermometer, it is easy to skew the reading of an alcohol thermometer by heating or chilling the bulb which holds the reserve fluid. For this reason, it's important to avoid handling the bulb when working with this type of thermometer, and to avoid exposing the...
However, the mercury-in-glass thermometer, commonly called a maximum thermometer, is the simplest and most widely used. Its operation is based on the fundamental principle that liquids expand when heated and contract when cooled. Consequently, when the temperature rises, the mercury expands and rise...

However, that event is unlikely to be fatal, especially since glass thermometers contain elemental mercury derived from cinnabar instead of the much more toxic methylmercury. It would take a lot more than a broken thermometer to cause long-term damage. Cinnabar in the Environment Cinnabar, ...

It is a sensor that converts sound energy to an electrical signal that can be amplified, transmitted, recorded, and reproduced. Even the common mercury thermometer is a sensor of sorts. Used to measure temperature, it has colored mercury in a closed tube. This sensor depends on mercury’s ...
