The air pressure at the foot of the mountain at an altitude of 200 m above sea level is 760 mm Hg. Art.

The air pressure at the foot of the mountain at an altitude of 200 m above sea level is 760 mm Hg. Art., and on the top of the mountain at the same time – 720 mm Hg. Art. Determine the absolute and relative altitude of the mountain if the pressure drops by 1 mm Hg. Art. for every 11 m ascent.

1) 760 – 720 = 40 mm Hg. Art. – the difference P between the foot and the top
2) 40 mm Hg. Art. × 11 m = 440 m – relative height of the mountain
3) 440 m + 200 m = 640 m – the absolute height of the mountain
Answer: h rel. = 440 m, h abs. = 640 m
