Question

Why is mercury used as a barometric liquid? Give
three reasons.​

Answer 1

Answer:

Mercury is commonly used in barometers because its high density means the height of the column can be a reasonable size to measure atmospheric pressure. A barometer using water, for instance, would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference.
