Calculate the atmospheric pressure at the summit of Vesuvius Heights 1895.

To solve this problem, you first need to indicate at what height the pressure changes by 1 mm. rt. Art.
As you know, a change in pressure by 1 mm Hg occurs with a change in height by 10.5 m.
Therefore, first we find the pressure difference between the foot of the mountain and the top.
To do this, divide the maximum height by 10.5 m.
We get. 1895 / 10.5 = 180.47 mm. rt. Art. [Difference in pressure between the top and bottom].
Add up to the pressure at the foot of the summit.
We get.
720 + 180.47 = 900.47 mm. rt. Art.
Round up to 900.
Answer. 900 mm Hg
