Question

Why is water not suitable as a barometric liquid

Answer 1

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 mercurybarometer to obtain the same pressure difference.

Answer 2

Hey buddy here is ur 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.

→ This is because mercury is 13.6 times more dense than water.
