What is the atmospheric pressure at the top of a hill with a height of 150 meters, if at the foot of it is 765 mm Hg?

With increasing altitude, atmospheric pressure decreases, since the mass of air that presses on us decreases. And vice versa – with a decrease in altitude, atmospheric pressure rises. As a result of a change in altitude of 10.5 m, atmospheric pressure changes by 1 mm Hg. Art.

Let’s find how much the atmospheric pressure will change at the top of a hill with a height of 150 m:

150: 10.5 = 14.3 mm Hg. Art.

Let’s find how many mm Hg. Art. will be atmospheric pressure at the top of the hill at an altitude of 150 m:

765 – 14.3 = 750.7 mm Hg. Art.

Answer: 750.7 mm Hg. Art.
