it is too dangerous if consumed or touched
Mercury, especially the vapour, is not good for health. As school thermometers are often broken, having a spill of mercury in the classroom is something best avoided.
Mercury is a very poisonous substance.
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 does not evaporate as fast as alcohol, so mercury thermometers stay accurate longer.
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
Mercury is not used in thermometers, because mercury is poisonous.
Mercury, if it enters your body, causes severe brain problems, and is usually deadly, so it is a poisonous material. it is no longer used in thermometers because thermometers were breaking and too many people were dying.
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 For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
