Aneroid barometers are advantageous because they are safer to use compared to Mercury barometers which contain toxic mercury. Aneroid barometers are also more portable, durable, and do not require periodic maintenance like mercury barometers do. Additionally, aneroid barometers are less prone to breakage and are not affected by temperature changes like mercury barometers.

What are two advantages of aneroid barrometer over mercury barrometer?
Two advantages of an aneroid barometer over a mercury barometer are that aneroid barometers are generally more portable and do not pose a risk of mercury exposure if broken, making them safer for handling. Additionally, aneroid barometers do not require the use of toxic mercury, which is better for the environment.
An aneroid barometer is different from a mercury barometer in that it does not contain?
An aneroid barometer does not contain mercury. Instead, it uses a small, flexible metal box called an aneroid cell to measure air pressure changes. Aneroid barometers are safer and more portable than mercury barometers.
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.
Types of Barometers?
The two common types of barometers are mercury barometers, which use the height of mercury in a column to measure atmospheric pressure, and aneroid barometers, which utilize a flexible metal membrane to detect and measure pressure changes without using liquid. Digital barometers are also becoming more popular, using electronic sensors to measure pressure.
An aneroid barometer is different from a mercury barometer in that it?
An aneroid barometer, invented by the French 19th century engineer and inventor Lucien Vidie, uses a small, flexible metal box called an aneroid cell. This aneroid capsule (cell) is made from an alloy of beryllium and copper. The evacuated capsule (or usually more capsules) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer.A mercury barometer has a glass tube of at least 84 cm in height, closed at one end, with an open mercury-filled reservoir at the base. The weight of the mercury creates a vacuum in the top of the tube. Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir. Since higher temperature at the instrument will reduce the density of the mercury, the scale for reading the height of the mercury is adjusted to compensate for this effect.

What is the difference between the aneroid barometer and a mercury barometer?
An aneroid barometer measures air pressure using a flexible metal box called an aneroid cell, whereas a mercury barometer uses a column of mercury to measure air pressure. Aneroid barometers are more portable and do not use toxic mercury like mercury barometers.

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.
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.

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 is the disadvantage of aneroid barometer?
One disadvantage of an aneroid barometer is that it can be more susceptible to mechanical wear and inaccuracies compared to mercury barometers. Aneroid barometers also require periodic calibration to ensure accurate readings. Additionally, they may not be as sensitive or precise at measuring very small changes in atmospheric pressure.
