advantages:::::::::::::::::-
:too dense
:has low vapour pressure
:doesn't evaporate easily
disadvantages:::::-
:bulky and fragile
:glass tube break easily
:hard to get reading under hard conditions
advantage of using a barometer is that we can measure air pressure .a disadvantage is that there is barely any wind.
A mercury barometer.
anaeriod barometer and a mercury barometer
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. (:
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.
A Mercury barometer is used to measure atmospheric pressure.
When you increase air pressure the mercury in a barometer will rise. Conversely when air pressure decreases the mercury in a barometer will drop.
Maybe you mean what does a mercury barometer measure. In which case the answer is atmospheric pressure.
no disadvantage
