Why is mercury rarely used in thermometers that take body temperatures?
Mercury is a toxic heavy metal. The possibility of breakage and the subsequent release of mercury into the body, or into the environment, means that mercury usage has gradually been phased out in consumer thermometers. Laboratory thermometers often still contain mercury, since it's useful over a wide range of temperatures. This isn't so critical in medical thermometers, since the body temperature of someone who isn't actually dead is almost certainly going to be no more than 10 degrees from 37 Celcius.
What are mercury thermometers used for?
If the bulb is red, blue, purple, green or any other color, it is not a mercury thermometer. Mercury thermometerscan be used to determine body temperature (fever thermometers), liquid temperature, and vapor temperature.
Why do you put thermometers on body for 1 minute?
Older thermometers took about a minute for the body temperature to warm the mercury in the glass bulb so that it reached body temperature and a reading could be taken. Modern thermometers are much faster and do not need to be kept for a minute.
Why is that mercury is used in thermometer?
Mercury is used in thermometers because mercury is the only liquid metal in room temperature. Hence our body temperature is observed by melting the liquid metal mercury due to our body temperature.
What liquid is inside thermometers?
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
What is the difference between clinical thermometers and other mercury-in-glass thermometers?
Clinical thermometers are specifically designed for measuring human body temperature, while other mercury-in-glass thermometers can be used for various purposes such as measuring temperature in laboratories or industrial settings. Clinical thermometers typically have a narrower temperature range focused on human body temperature, while other thermometers may have a wider temperature range. Additionally, clinical thermometers are often designed with features like an easy-to-read scale and a flexible tip for comfort and safety during use.
The metal mercury used for?
It is used in the thermometers as it detects the heat change.It points out the variation of temperature of human body.
Why is mercury no longer used in thermometer?
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.
What is the danger of using lab thermometers in human body?
im not sure if this is what you mean, but some lab thermomometers contain mercury and when mercury enters the human body its extremely toxic and can cause brain damage and other such things.
How do you remove mercury in your stomach?
You wouldn't have any there unless you've been snacking on thermometers. Mercury typically gets stored in fatty tissues in the body, and those metabolize very slowly. About the only thing you can do is to remove the source on the mercury, and the body will cleanse itself at the pace it can.
What are the use of mercury?
mercury is used in thermometers,remote batteries,light switches,and paints It is also commonly used in home thermostats for the control of heating and/or cooling.
Is mercury used in food thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
