Determine the air temperature and atmospheric pressure at an altitude of 2 km. If at the foot of the mountain +18 and atmospheric pressure 740 mm Hg. If the atmospheric pressure decreases for every 100m by 10 mm Hg

1) The air temperature drops by 6 ° C for every kilometer of ascent. This means that with a rise of 2 km, the air temperature will drop by 2 * 6 = 12 ° C.
Now let’s find the temperature at the top. Subtract the temperature drop from the temperature at the foot.
+18 – 12 = + 6 ° C – temperature at the top.
2) Atmospheric pressure decreases by 10 mm Hg. Art. for every 100 meters. This means that with an ascent of 2 km = 2000 m, the pressure will decrease by 2000/100 * 10 = 200 mm Hg. Art.
Now let’s find the pressure at the top. Subtract the pressure drop from the pressure at the foot.
740 – 200 = 540 mm Hg. Art. – atmospheric pressure at the summit.
Answer: + 6 ° C; 540 mmHg Art.
