Mainly irrational fears being manipulated for political opportunity. Some mercury compounds are toxic and should be handled with due care, but most issues were caused decades ago by gross misuse, (selling it as a medicine for people to directly drink) industrial scale pollution, and chronic exposure in the workplace (eg hat makers breathed in fumes of hot mercury while felting rabbit fur). Metallic mercury in thermometers is completely sealed and even if the glass breaks the amount is tiny and the metallic form is not absorbed through skin in amounts measurable against natural background levels. (if swallowed it can react with stomach acid and then be absorbed)
=The older thermometer's that I have used contain mercury the new ones are digital.==See the link for detailed answer.=
Water was initially used and later on alcohol was used.
It is because it is electric
it is mercury. its actually a liquid at room temperature.
Mercury is highly toxic (poisonous). The gas evaporating from the spilled liquid mercury is dangerous.
the element used in termometers is Mercury.
Modern thermometers are typically made of materials such as glass, plastic, or metal. The most common type of modern thermometer is the digital thermometer, which includes a temperature sensor and a digital display screen. Other types of modern thermometers may contain mercury or alcohol as the temperature-sensitive material.
Most thermometers used to contain Mercury until it was found to be toxic.
No, most instanst thermometers used for cooking are digital and therefore don't contain mercury. There may be some older style thermometers that do contain mercury.
They are edible
Most thermometers used to contain mercury until it was found to be toxic.
Mercury used to be a popular element for thermometers, but I think it's illegal to make a mercury thermometer because if you break one you have a hazardous situation on your hands. Today thermometers that contain liquid, almost always contain alcohol.
Mercury is used in thermometers barometers and flourescent lightbulbs.
Most pool thermometers do not contain mercury. An easy way to tell if a pool thermometer contains mercury is if it sinks to the bottom of the pool rather than float.
how about water, or Mercury as used in thermometers. both conductive.
Many thermometers contain alcohol because it is less toxic than mercury. In addition to this, the contents of an alcohol thermometer can evaporate away quickly.
