What two units of air pressure are used commonly in weather reports?
The answer to this question is, the Mercury and aneroid barometer
What are the difference between the mercury barometer and aneroid barometer?
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
What type of barometer is the most commonly used today?
The aneroid barometer most commonly used today would be the tiny quartz transducers built into GPS units, sports wrist watches and the like.These would outnumber mercury column types, and other aneroid ones.
What instruments are used to measure the atmospheric pressure?
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
Instrument used for measuring highest and lowest temperature of a day?
Aneroid Barometer
Types of Barometers?
anaeriod barometer and a mercury barometer
Which statement accurately describes a difference between a mercury barometer and an aneroid barometer?
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
An aneroid barometer is different from a mercury barometer in that it does not contain?
Mercury
How are mercury and an aneroid barometer alike?
D
What is the difference between Mercury barometer and a aneroid barometer?
their spelling is different.
What is the difference between the aneroid barometer and a mercury barometer?
their spelling is different.
What type of barometer was invented first the aneroid or the mercury?
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
What is an aneroid barometer called?
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
Which liquid is used in an aneroid barometer a mercury b alcohol c none?
mercury
What is the most commonly used barometer?
The most commonly used barometer is the mercury barometer.However, it is not easy to transport but it gives more accurate results. Another type of barometer is Aneroid barometer which is easy to transport and handle.
What is the difference between how air pressure is indicated in a mercury barometer and an aneroid barometer?
Usually no difference at all. They can both move a pointer around a circular scale. The scale can be calibrated in both Inches of Mercury (InHg) or Millbars (Mb). An aneroid system can lend itself more easily to a digital display.
What led to the development of the aneroid barometer?
Evangelise Torricelli invented the mercury barometer in the 1600s. It was very accurate, but it was clumsy to move and had to stay upright. If humans hadn't invented the aneroid barometer, you would see big mercury barometers in all types of transportation.
