It is not used to measure below -39°c and above 375°c
Doesn't work accurately upside down
mercury is expensive
disadvantages of coccus bacteria?
It causes health problems because it has side effects AND a long life, thus remaining in soil, water, animals and people for a long time.
Drill the tree till you can see the center of the tree and inject mercury!
I am sure there are other types of mercury related catalysts in terms of chemistry, but one that stands out is mercury-aluminum amalgum, which is used as a reductive catalyst in organic chemistry.
Advantages: Being Able to hear Disadvantages: Being Deaf, Having an ear infection isnt it obvious?
An advantage of using a barometer is that you can measure air pressure.
A mercury barometer.
anaeriod barometer and a mercury barometer
grams
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
A barometer using water,would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference. This is because mercury is 13.6 times more dense than water.
Mercury barometer precaution
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. (:
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.
barometer has mercury inside it .
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.
