Question

Give two reasons for the use of mercury as a barometric liquid.

ICSE Class 9 Physics Chapter Pressure in Fluids and Atmospheric Pressure

Answer 1

Explanation:

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....

Hope it will help u...

Thanks...❤❤❤

Answer 2

Answer:

beacause it's high density means the height of column can be a responsible size to measure atmospheric pressure. a barometer using water, for instance , would need to be 13.6 taller than mercury barometer to obtain the same pressure difference
