At the top of the mountain 2 km high, the air pressure was 560 mm Hg. What will be the air pressure

At the top of the mountain 2 km high, the air pressure was 560 mm Hg. What will be the air pressure at the foot of the mountain?

Before starting to solve the problem, let us recall the rule that we will need to use to obtain correct calculations: with a decrease in altitude for every 10 meters, atmospheric pressure will increase by 1 mm Hg. This will allow you to see how the pressure changes. To do this, run:

2000 ÷ 10 = 200 mm Hg

Now we can calculate what the pressure at the foot of the mountain will be. Means,

560 + 200 = 760 mm Hg

Consequently, at the foot of the mountain, the barometer will show 760 mm Hg.
