Question

Quizplus · Accepted Answer

Mercury has a high density, which means that a small column of it can exert a large pressure at the bottom of a barometer tube. This allows for more accurate readings of atmospheric pressure. Additionally, mercury has a low vapor pressure and does not stick to glass or metal, making it a convenient liquid for use in barometers.
