The height of the mountain is 300 meters. What is the atmospheric pressure at its top

The height of the mountain is 300 meters. What is the atmospheric pressure at its top, if at the foot of the mountain it is 750 mm of mercury.

In the troposphere, with an increase in altitude for each kilometer, atmospheric pressure decreases by 100 mm Hg. st. / km

1) Let’s convert meters to kilometers: 300 m = 0.3 km

2) Find out how much the atmospheric pressure will drop when climbing to a given altitude:

0.3 km * 100 mm Hg. Art. / km = 30 mm Hg. Art.

3) Find out what is the atmospheric pressure on the top of the mountain.

To do this, subtract the pressure drop from the pressure at the base:

750 mm Hg Art. – 30 mm Hg. Art. = 720 mm Hg. Art.

Answer: 720 mm Hg. Art.
