Question

how will be barometric height be affected if mercury was replaced by water in a simple Barometer ​

Answer 1

Answer:

. The column of water inside the barometer would be 13,6 times higher, since the density of mercury is 13,6 times that of water. In reality, that will not be the case, because water boils under vacuum at room temperature.

Explanation:

Answer 2

Answer:

a) Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir.

When the tube is pushed down into the trough of mercury the height of mercury column above the surface of the bottom surface remains the same.
