Question

if a sample of gas at sea level were moved to an elevation at which the pressure changed to 912 mm Hg, what would be the new elevation of the sample in kilometers

Answer 1

Solution:

$760 mmHg = 10^5 Pa$

$912 mm Hg = 1.2 \times 10^5 Pa$

$P = hdg$

$1.2\times10^5 = h \times 1.225 \times 9.8$

h = 10 km

Answer: 10 km
