∙ 14y agoMercury is within the thermometer's glass tube. There is a bulb which holds the majority of the mercury. Mercury reacts to temperature and rises withing the tube. A scale is used to determine the approxiamate temperature. Mercury thermometers are widley used in meteorology, but are rare in medical use. Some countries have legally banned them.

∙ 11y agoThe liquid in a mercury thermometer is ... Mercury.
Mercury is an element which is liquid from -38.83 °C to 356.73 °C, making it useful for measuring temperatures for most of the environments we encounter in person. Below that range, mercury solidifies and we would have to find another liquid to use in a thermometer or find another way to measure temperature (such as a thermocouple). Above that temperature range, mercury starts to boil (unless kept under pressure) so it's not suitable for measuring high temperatures. In theory we could still use a liquid thermometer with something that is liquid at high temperatures, but it gets rather complicated and there are easier and safer ways to measure high temperatures.

Does barometers contain Mercury?
Many do, but not all. Most barometers that people would have in their homes are aneroid barometers, which don't contain any 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.
Why are aneroid barometers often more practical than mercury barometers?
The aneroid barometer is more durable and compact, and much easier to read. The only particular advantage of a mercury barometer is that it's a direct measurement -- there's no calibration involved. If you can measure the height of the column above the pool and you know the density of mercury, you have the pressure.
What are 10 tools the scientist use in their work?
Barometers, Anemometer, Thermometer
Instruments that scientist use to work?

Types of Barometers?
anaeriod barometer and a mercury barometer
How are the Mercury and aneroid barometers alike?
mercury barometers and aneroid barometers both measure air pressure.
What are 2 types of barometers?

What element is used for barometers?
Mercury
Why are barometers often more practical than mercury barometers?
They are more portable and can be used for airplane equipment
What instrument uses Mercury?
Historical, both thermometers and barometers have used mercury.
What element is a liquid metal used in barometers?
mercury
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
What are barometers made of?

How is mercury used in the modern world today?
Mercury is used in thermometers barometers and flourescent lightbulbs.
