Mercury comes from several types of mineral deposits world wide, but the most common type of mineral is called cinnabar. Cinnabar is mercury chemically bound to sulfur, i.e. HgS. Heating this mineral causes the sulfur to combine with oxygen creating sulfur dioxide, SO2, as a gas. (The gas is now considered a pollutant.) What remains is the mercury. Although mercury is a relatively rare element, there are dozens of sites around the world where it is actively mined.
the element used in termometers is Mercury.
thermometers are made out of mercury and alcohol because mercury expands when it is heated
Mercury has recently been removed from almost all thermometers because the risk of breaking the thermometers and spillage of the harmful liquid.
Mercury is no longer used much in thermometers due to the poisonous compounds that it forms. When I grew up, in Chemistry at school and at the doctors there were mercury thermometers and alcohol thermometers.
Mercury has many uses but the first one that comes to mind, is the use for this metal in thermometers. Mercury is, to my knowledge, the only metal that can be a liquid at room temperature. This metal is also used in making other instruments such as barometers.
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
Mercury is not used in thermometers, because mercury is poisonous.
Mercury in thermometers is in a liquid state, since mercury is liquid at room temperature.
Mercury is common in both fish and thermometers. Although nowadays they make thermometers without mercury in them.
Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]
In ordinary bulb thermometers, yes.
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
the element used in termometers is Mercury.
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
When mercury filled thermometers break, the mercury is released. Mercury is toxic to people, pets and the environment. There is a long history of mercury from broken thermometers and other medical devices being improperly dealt with, or even ignored. Since there are adequate replacements for mercury thermometers, OSHA, EPA, AMA and others discourage the use of mercury thermometers and encourage their replacement with thermometers using other technologies.
Mercury is used in thermometers.
