How are mercury thermometers used today?
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 For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
Do thermometers contain mercury?
Some do, some have other liquids instead, such as colored alcohol.Some do, some have other liquids instead, such as colored alcohol.Some do, some have other liquids instead, such as colored alcohol.Some do, some have other liquids instead, such as colored alcohol.
Where online can I find laser thermometers?
Laser thermometers can be found at numerous places online. It depends on which type of laser thermometer that you are looking for. You have culinary thermometers and medical thermometers. Most medical sales sites will have these, as well as culinary stores.
What is the advantage and disadvantage of using water in a thermometer?
Thermometers are devices which can be used to measure the body temperature. The body temperature is an important health indicator, and to assess it properly the core temperature must be measured. The best way to this is through a rectal or aural measurement - these require specific thermometers. Aural measurements are most common in professional settings because of their reliability and ease of use, though a rectal measurement is still the most accurate. Nowadays most thermometers are electric, for greater accuracy and safety. Mercury thermometers are no longer used in medical applications, due to the toxicity of mercury, and many countries have banned the classic mercury-in-glass thermometers from such purposes.
Why did schools use mercury thermometers?
Schools used Mercury thermometers b/c it was the most common type around.
What liquids have been used in thermometers?
they used to use mercury but now they use a type of alcohal
Thermometers operate on the premise that liquids?

What are the two most commonly found in liquid-in-glass thermometers?
if you mean what are the two most commonly found liquids in a liquid-and-glass thermometer then the answer is mercury and alcohol :) hope this helps
What are the demographics of thermometer use?
All health care professionals use thermometers. All health care facilities have thermometers. Most homes also have thermometers.
Why did People Change Mercury Thermometers to Other Liquids?
because
What are two liquids that have been used in thermometers?
Mercury and alcohol (ethanol).
Why do you use liquids not solids or gases in thermometers?
because liquids can give us the right temperature but solids and gases
Why liquids are used in thermometers?
They are used in thermometers to let us see the heat of the object you are measuring, if you use solid, it wouldn't be able to move up, if you use gas, it will fill the whole container, so it's better to use liquid
Is there mercury in pool thermometers?
Not all pool thermometers have mercury in them. Some types do, but those that use digital or laser technology most likely do not.
Why use Mercury in thermometers?
Thermometers used to have Mercury in them because it is very temperature reactive and a liquid across most temperatures measured in everyday life. However, this practice has been discontinued due to the health risks associated with contact with mercury from broken thermometers; most analog thermometers today use colored ethanol as the measuring fluid.
How are mercury thermometers used today?
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.
How does a labrotory thermometer work?
There are several types of thermometers in use in laboratories.The simplest is the liquid filled thermometer which converts the expansion of a liquid (mercury or alcohol) into a temperature reading.Bimetallic thermometers use the differential expansion of metals at given temperatures to indicate atemperature.Thermocouple thermometers use the current generated by dissimiiar metals at a temperature to provide a input to an appropriately scaled electrical meter.Liquid crystal thermometers rely on the different melting points of solids to show temperature.Temperatures of objects may also be determined by measuring the infrared emissions from its surfaceAlthough not in use in labs there are also interesting thermometers using the density of liquids at different temperatures to allow calibrated floats to rise or sinkTHANX
