At the peak of Mt. Everest, atmospheric pressure is 220. mm Hg. What is this pressure in pounds per square inch (psi)?
(1 atm = 760 mm Hg and 1 atm = 14.7 psi)

Question

Quizplus · Accepted Answer

To convert the pressure from mm Hg to psi, we need to use the conversion factor:

1 atm = 14.7 psi = 760 mm Hg

We can rearrange this equation to get:

1 mm Hg = 14.7/760 psi

So, if the pressure at the peak of Mt. Everest is 220 mm Hg, we can calculate the pressure in psi as:

220 mm Hg x (14.7/760 psi/mm Hg) = 4.26 psi

Therefore, the answer is C.
