What was the device that Torricelli invented for measuring air pressure called?
Mercury Barometer
How do you use a manometer?
A manometer is a device that is used to measure the pressure of a fluid. The U-shaped glass tube is partially filled with a liquid, usually mercury. The difference between the height of the mercury corresponds to the difference between the pressure of the fluid in the container and the atmospheric pressure.
Which is the air pressure measurement device?
An air pressure measuring device is called a Barometer.
What is the difference between high and low pressure mercury lamps?
how are low pressure mercury lights made and how do they operate?
Does mercury exert more pressure than water?
mercury exerts more pressure than water bcause mercury is a metal and water is a non metal obviously mercury weighs more than water
What was the device that Torricelli invented for measuring air pressure called?
Mercury Barometer
What device did Evangelista Torricelli invent to measure atmospheric pressure?
Evangelista Torricelli is known for his invention of the barometer in 1643. His original device consisted of a long tube of glass (which contained a vacuum) on top of a larger container of mercury. The pressure from air pressing down onto the exposed surface of the mercury would push the mercury upwards into the tube; thus, the higher the air pressure, the higher the mercury level. Air pressure was then measured using "millimeters of mercury", which corresponded to the mercury level within the tube.
Torricelli invented a device for measuring air pressure called a(n)?
To measure the local pressure of the Earth's atmosphere, Torricelli invented the first Mercury Barometer.

What is a mercury barometer?
A mercury barometer is a device that measures air pressure. The key component that distinguishes it from other barometers is the metal mercury.
What takes your blood pressure?
Your blood pressure can be taken with a mercury blood pressure gauge, an aneroid manometer, or an electronic device for measuring the blood pressure, as long as the device has been recently calibrated and validated. With rare exceptions, blood pressure gauges found in supermarkets or pharmacies aren't properly maintained and shouldn't be used.
If the atmospheric pressure is 29.4 inches of mercury what is the corresponding pressure of mercury?
If the atmospheric pressure is 29.4 inches of mercury the corresponding inches of mercury is: 880.
How can you determine air pressure?
Air pressure is usually measured using a barometer. This device usually has mercury inside it along a tube that is a compete vacuum. As the air pressure rises the pressure of the air pushes down on the mercury and forces it to rise further into the vacuum. 760 mm of mercury is considered to be 1 atmosphere. For very high pressures an aneroid barometer is used. This has wafers inside that are compressed under high pressure that give a reading.
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
What are Mercury Barometers and Aneroid Barometers?
A barometer is used to measure air pressure. A Mercury Barometer uses a column of liquid mercury supported by air pressure. The length of this liquid column gives a measure of the air pressure. Air pressure is commonly expressed in terms of "millimetres of mercury" (mmHg). Mercury is considered as a hazardous material and Mercury Barometers cannot be legally manufactured in Europe as of 2007. An Aneroid Barometer traditionally uses an evacuated corrugated metal canister that expands or contracts in response to changes in air pressure and this mechanical movement is amplified to indicate the air pressure in any required units on a calibrated display. The commonest pressure units displayed are in "millibars" (mbar). The latest Aneroid Barometers use a tiny evacuated capsule made of semiconducting materials that responds electrically to changes in air pressure, enabling very precise and repeatable measurement. The electrical signals from this device are processed electronically to provide a visual display of air pressure or to be recorded on a data-logging device as required.
What is a sphygmomonometer?
A sphygmomonometer is more commonly known as a blood-pressure cuff. It is a device used to measure a person's blood pressure. It typically consists of an inflatable arm sleeve, an air pump or bulb, a pressure gage (that measures pressure in milligrams of mercury), and a stethoscope.
Why does your cruise control not work on 2005 mercury?
Check the pressure sensor on the master cylinder - very common.
