Mercury barometers:
A)use mercury because it has a low density.
B)are more cumbersome than water barometers.
C)give direct measurements in millibars.
D)are inverted into a pool of mercury.

Question

Quizplus · Accepted Answer

Mercury barometers are inverted into a pool of mercury. This is because mercury is denser than water and does not evaporate quickly, making it more suitable for measuring atmospheric pressure. They do not give direct measurements in millibars, but rather use the height of the mercury column to determine atmospheric pressure. They are also typically more compact than water barometers, making them more practical for everyday use.
