At the foot of the mountain, the barometer shows 760 mm Hg and 722 mm Hg at the top.

At the foot of the mountain, the barometer shows 760 mm Hg and 722 mm Hg at the top. What is the height of the mountain if for every 12 m of ascent the pressure decreases by 1 mm Hg.

Let’s calculate by what amount the atmospheric pressure changed when climbing a mountain:

760 mm Hg – 722 mm Hg = 38 mm Hg

By condition, the pressure decreases by 1 mm Hg, when lifting by 12 m.Then:

38 * 12 = 456 (m).

The pressure will be 722 mm Hg. at an altitude of 456 m.
