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.

Which instrument is often filled with mercury or colored water or alcohol?
Thermometers are the instrument that is often filled with mercury, colored water, or alcohol. Most early thermometers were made with mercury.
What is an amalgram?
If you mean AMALGAM it is a mercury alloy often used in dental filings. :)
What are inches of vacuum?
Pressure is often measured in inches of mercury when describing barometric pressure in weather reports. This term is also known as "inches of mercury vacuum".
What is practical problems?
Practical problems refer to real-world issues or challenges that require practical solutions, often involving the application of knowledge, skills, and resources. These problems can arise in various domains, such as engineering, healthcare, education, and daily life, and typically demand critical thinking and problem-solving approaches. They often involve constraints such as time, budget, and available resources, making it essential to find feasible and effective solutions.
How does a mercury boiler work?
A mercury boiler operates by utilizing mercury as a heat transfer fluid. In this system, mercury is heated to high temperatures, allowing it to vaporize and transfer heat efficiently. The vaporized mercury then circulates through the boiler, transferring heat to the water or steam system, which can be used for heating or power generation. The use of mercury, however, poses significant environmental and health risks, making such systems less common and often subject to strict regulations.
Why are barometers often more practical than mercury barometers?
They are more portable and can be used for airplane equipment
What does a aneroid barometer look like?
Aneroid barometers usually look like a clock. A compact round cylinder with a glass front and a dial with pointer. Unlike mercurial barometers there is no need for a long case. Aneroid types use a small, collapsible, sealed metal can, to detect changes in pressure. The minute deformity of the can, is amplified by levers to turn the dial. all this can be held in a small instrument case, the size of a wall clock.
What element is used for barometers?
Mercury is commonly used in barometers due to its high density and ability to accurately measure air pressure. However, due to its toxicity, alternatives such as water, oil, or electronic sensors are often used now.
Is a liquid metal used in barometers?
Science and industrial labs often use mercury filled barometers due to mercury's high density and low vapour pressure. This allows the barometers column of liquid to be less than 1 meter high (760 mm Hg=1 atmosphere). As an additional advantage the meniscus of the mercury is upwards at the center, unlike water, making accurate reading simpler. However mercury's toxic attributes make it hazardous if spilled, so mechanical diaphragm barometers are often used.
What does a bronometer look like?
A barometer typically consists of a sealed glass tube filled with mercury or an aneroid mechanism. In a mercury barometer, the tube is inverted in a reservoir of mercury, allowing the mercury level to rise or fall based on atmospheric pressure changes. An aneroid barometer uses a flexible metal diaphragm that expands or contracts with pressure changes, moving a needle on a dial to indicate the pressure level. Both types are often encased in decorative housing, making them suitable for display.
What is Mercury's metal reactivity?
Mercury is a relatively unreactive metal. It is resistant to oxidation and corrosion, which is why it is often used in thermometers and barometers. However, it can react with strong acids and halogens to form compounds.
Which barometer measures air pressure by using a metal chamber that is sensitive to pressure change?
The barometer that measures air pressure using a metal chamber sensitive to pressure changes is called an aneroid barometer. It operates by using a flexible metal capsule, which expands or contracts in response to changes in atmospheric pressure. These movements are then translated into a measurement of pressure, often displayed on a dial. Aneroid barometers are commonly used in altimeters and weather forecasting.
How is a barometer used to measure weather?
A barometer measures atmospheric pressure, which is crucial for weather forecasting. As air pressure changes, it can indicate shifts in weather patterns; for instance, falling pressure often signals approaching storms, while rising pressure suggests fair weather. By monitoring these changes over time, meteorologists can make predictions about upcoming weather conditions. There are two main types of barometers: mercury and aneroid, both serving the same purpose in different ways.
Is Mercy a solid liquid or gas?
Mercy is not a recognized substance; however, if you meant "mercury," it is a metal that is liquid at room temperature. Mercury is unique among metals as it remains in a liquid state, exhibiting properties typical of both liquids and metals. It is often used in thermometers and barometers due to its ability to expand and contract with temperature changes.
What does Hg stand for in the eye of a hurricane?
It refers to the barometric pressure in the hurricane's eye. A lower barometric pressure generally means a stronger storm. Hg is the chemical symbol for the element mercury, a metal that is liquid at room temperature. Barometric pressure is often given in units of either mmHg (millimeters of mercury) or inHg (inches of mercury). Both units refer to the early barometers, which consisted of a vacuum tube with its open end immersed in a dish of Mercury. Pressure was measured based on how high up the mercury moved in the tube, which climbed higher with higher pressures.
What is the mercury?
Mercury is most often found in thermometers.
What are the pros of living on mercury?
Mercury is the only metal which is a liquid at room temperature.One pro is that it conducts electricity well and is often used for electrical switches.It is also used for refining gold.One major con is that it is toxic. It is most dangerous when it is airborne.
