Determine the atmospheric pressure at the foot of a hill 60 m high if the barometer showed

Determine the atmospheric pressure at the foot of a hill 60 m high if the barometer showed a pressure of 758 mm at its top.

An approximate change in atmospheric pressure with a height of 1 millimeter of mercury occurs at a height of about 10 meters.

We find the ratio of the height of the hill to the given value of the height.

We get:

60/10 = 6 mm Hg

Since the pressure decreases with height, it means that in order to determine the atmospheric pressure at the foot of the hill, it is necessary to add the difference to the pressure at the top.

In this case, we get:

758 + 6 = 764 mm Hg

Answer:

The pressure at the foot of the hill will be 764 millimeters of mercury.
