Why are aneroid barometers often more practical than mercury barometers?
Wiki User
∙ 13y ago
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".
How long should the aim of a science experiment be?
If you are writing a practical report it can be very small! Often the aim is, simply stated, the hypothesis you are trying to test.
A person knowledgeable in a wide range of fields is often called what?
I've heard them called a "renaissance man/woman" If they are older, and have lots of practical knowledge in a field, sometimes they are referred to as a "geezer tech."
Why are barometers often more practical than mercury barometers?
They are more portable and can be used for airplane equipment
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 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.
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 practical benefits?
Practical often means tangible and useful, and a benefit is something gained. So if something is a practical benefit, it is something that can help you in a meaningful way.
What is often hidden in the suns glare?
Mercury
Does sulfur contain Mercury?
Both Sulfur (S) and Mercury (Hg) are elements. However, Mercury has a great affinity for Sulfur, and is often found in Mercury Sulfides. Cinnabar (Mercury Sulfide, HgS) is a common Mercury Ore.
What jobs are really practical to telecommute to?
Secretary jobs are actually the most practical to telecommute to. But temp jobs are often included as well.
How often do you take your child on outings life experiences and at what kind places?
As often as is practical and as varied as possible.
What element is often lost to the biosphere for all practical reasons?
Phosphorus
