Question

How is height of a liquid column affected by atmospheric pressure ?explain with the help of an activity

Answer 1

Answer:

A better solution is to take a tube filled with say, water. Close the tube at one end and open at the other. When vacuum forms at the closed end, the pressure of the column of water equals that of the air. The problem is, to do that you will need a tube ten meters high! (and that is why a suction pump can’t lift water over ten meters).

We then use the heaviest fluid we know of, mercury. The column can then be reduced to 760 mm (29.9 inches). In Europe, today, we measure the pressure in hecto-Pascal (hPa) and the average pressure at sea level is then 1013.25 hPa. But in the USA, it is still measured as inches of mercury (InHg).
