Experiment: Using the bottle-and-stopper system with tubes, determine the number of atmospheres of pressure required to support a water column of height in the 30-40 cm range. You do this by using the fact that PV = const in the closed-end tube, and the original pressure was atmospheric.
Using this result determine by what proportion the atmospheric pressure increased. For example, if the pressure increased from 1 atmosphere to 1.06 atmosphere, the increase was .06 atmosphere.
Measure the height of the column and determine the extra pressure, in N / m^2, necessary to support this column (by 'extra pressure' we mean the pressure in addition to the atmospheric pressure originally in the bottle).
Then use your results to determine atmospheric pressure in N / m^2.
