Determine the atmospheric pressure at the top of the mountain if it is known that at the foot of the mountain the atmospheric pressure is 760 mm Hg, and the air temperature is 18 ○ С. At the top, the air temperature is 15 ○ С
Let’s determine the temperature difference between the foot of the mountain and the top.
18 ° – 15 ° = 3 °
It is known that with an increase in altitude by 1000 meters, the temperature decreases by 6 °.
Let’s determine the height of the mountain.
(3 ° / 6 °) * 1000 = 0.5 * 1000 = 500 meters.
With a change in height by 10.5 meters, atmospheric pressure changes by 1 mm Hg. Determine the pressure difference between the base and the top.
500 / 10.5 = 47.6 ° ≈ 48 mm Hg.
Let’s determine the pressure at the top of the mountain.
760 – 48 = 712 mm Hg
Answer. The pressure at the top is 712 mm Hg.
