The atmospheric pressure at sea level is 760 mm Hg. what pressure will be at an altitude of 500 m above sea level?

Before proceeding with the solution of the problem, it should be remembered that the atmospheric pressure will drop with rise (approximately every 10 m per 1 mm Hg). In this case, the altitude is 500 m above sea level, so to calculate how the atmospheric pressure will change with increasing altitude, you should do the following:

500 ÷ 10 = 50 mm Hg

We know the pressure at sea level, so we can see how it will change with increasing altitude. Hence,

760 – 50 = 710 mm Hg

Thus, at an altitude of 500 meters above sea level, the atmospheric pressure will be 710 mm Hg.
