Answered by nikhapraseelan274

Answer:

Explain why water cannot be used in place of mercury in a barometer? The atmospheric pressure at sea level = 76cm of Hg = 1.013x105 Pascal. That is, if water is used in barometer tube instead of mercury, the length of the tube must be greater than 10.326 cm. ... So, we cannot replace mercury by water in the barometer.
