It is used in the barometer because it is the densest liquid known, requiring only 33 inches of Mercury to indicate atmospheric pressure. Water on the other hand would require 39 feet to indicate the same pressure.
It is used in thermometers for a different reason. The expansion of mercury is a stable amount. Meaning it changes in volume the same amount from 0 to 1 degrees as it does in volume from 100 to 101 degrees, making it a desirable fluid for scaling thermometers.
Presently in the US it is illegal to manufacture these devices using mercury.

What are the two substances used in a liquid column thermometer?
iodine and mercury
What is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
Is it a solid liquid or gas found in a thermometer?
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
The difference between a clinical and mercury thermometer?
All righto, ya gotta 'no wat da clinic n' da mercury thermometer is da... Foistly, clinic thermometer is da thermometer used to measure body temperature. Often the liquid inside it is mercury, but sometimes it is alcohol. It is very accurate because it has a narrow place where the liquid rises very fast. Den da mercury thermometer consists of mercury. Basically, it has..... yea blah blah blah, just look it up in ya dictionary. Anyways, da thing is there must be a problem with da questieon. Mercury thermometer has a almost accurate point but clinical thermometers have a very accurate things becausse it has a narrow place where the liquid rises very fast.
What liquid can be used in a thermometer?
Ethanol-filled thermometers are used in preference to mercury for meteorological measurements of minimum temperatures and can be used down to −70 °C (-94 °F). The physical limitation of the ability of a thermometer to measure low temperature is the freezing point of the liquid used.Alcohol
How a barometer can be used to measure the vapor pressure of a liquid?
A mercury thermometer, that is a barometer can be used to measure vapor pressure. Initially, a proper temperature must be recorded. Then the liquid should be injected into the mercury column. This new measurement subtracted from the original will yield the vapor pressure of a liquid.
The liquid most commonly used in a thermometer is either mercury or?
The liquid commonly used in a thermometer is mercury or COLOURED ALCOHOL.
How can Mercury be used as a liquid in a thermometer?
it is used in liquid form as in room temperature the mercury is in liquid
What is in a thermometer and a barometer?
A thermometer measures temperature - most are now electric but they used to have alcohol or mercury in them. A barometer measures air pressure - they are now electric but used to have air in them (in a bellows with a spring).
Which liquid is used in an aneroid barometer a mercury b alcohol c none?
mercury
What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
What element is often used as the liquid of thermometer?
Mercury
What are the two liquid used in the thermometer?
iodine and Mercury
What element is used in a barometer?
Barometers can use any liquid. A dense liquid that makes for a short column at room temperature, is mercury.
What was the first liquid used in a thermometer?
The first thermometer was a tube filled with water and air.
What is an instrument that measures changes in air pressure using liquid mercury?
Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using mercury for the purpose. 1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent. 2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft. 3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.
What metal element is used to make thermometers?
it is mercury. its actually a liquid at room temperature.
