Question

Why is not water used as a barometric liquid?give the two reason

Answer 1

Answer:

( a ) The density of water is low ( = 1000 kg / m^3 ) , so nearly 10.4 m height of water column is needed to balance the normal atmospheric pressure . But it is highly inconvenient to take a tube of height 10.4 m for a barometer .

( b ) Water sticks with the glass tube and wets it , so the reading becomes inaccurate .

Hope it helps !!

Answer 2

Answer:

water cannot be used as barometric liquid because it's density is lower than Mercury . water's density is 1000 gram per cubic meter. hence it requires a barometer whose height is around 11 meters
