Derivation of the Barometric Pressure Formula 1. Find the air pressure in a mine at a depth of 1km at the temperature of 40 degrees Celsius. (Answer: 848 mmHg) 2. The temperature of the earth's atmosphere drops about 5°C for every 1000 m of elevation above the earth's surface. If the air temperature at ground level is 15°C and the pressure is 760 mm Hg, at what elevation is the pressure 380 mm Hg? Assume that the air behaves as an ideal gas. (Answer: 5,551.1031 m)
