Water was initially used and later on alcohol was used.

it is mercury. its actually a liquid at room temperature.
Mercury. It isn't used much these days in thermometers these days as it is very toxic.
=The older thermometer's that I have used contain mercury the new ones are digital.==See the link for detailed answer.=
Some mercury is used in flourescent lamps, including CFLs. Many streetlights use mercury-vapor lamps. Many dentists still use mercury-silver amalgam to fill teeth. In the past it has been used in thermometer's or a means of closing circuits such as thermostats and tilt sensors. I am trying to help find a way to super-cool mercury to create a super-fluid that will power an anti-gravity electromagnetic torus. The problem is that mercury freezes solid it needs an anti freeze solution.
Mercury is a liquid at room temperature and has a specific gravity which is higher than water and is not nearly as likely to vaporize as water or alcohol.
Mercury is not used in thermometers, because mercury is poisonous.
Mercury is used in thermometers.
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.
mercury was used for thermometers and baramoters
Most thermometers used to contain Mercury until it was found to be toxic.
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 For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.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 thermometers.
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?]
mercury is used in 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.
