The pressure at the foot of the mountain is 660 mm Hg, the pressure at the height is 520 mm Hg

The pressure at the foot of the mountain is 660 mm Hg, the pressure at the height is 520 mm Hg, which equals the height of the mountain.

To solve this task, we need to understand that the mercury column rises every 12 meters by one unit. Accordingly, initially we calculate the difference in pressure of 660 mm Hg. – 520 mm Hg = 140 mm Hg, and after this calculation we determine the height of the mountain: 140 mm Hg. x 12 m. = 1680 m. Mountain height -1680 meters
