Chapter 12, Problem 47A

Interpretation Introduction

Interpretation:

The atmospheric pressure at top of Mount Everest is $33.6kPa$. It should be converted to atm and compared with the pressure at sea level

Concept introduction:

 Atmospheric pressure is the force exerted by the air on a surface as gravity pulls it to Earth.

Answer to Problem 47A

$33.6kPa$ $=0.332atm$

The pressure at sea level is $1atm$ so the pressure atop Mount Everest is about one-third of the $1atm$ pressure at sea level.

Explanation of Solution

Given: Atmospheric pressure = $33.6kPa$

Explanations:

$1atm$ = $101.325kPa$

$\therefore 33.6kPa=33.6kPa\left(1atm/101.35kPa\right)$

$=0.332atm$

The pressure at sea level is $1atm$ so the pressure at the top of the Mount Everest is about one-third of the $1atm$ pressure at sea level.

$$

Conclusion

$33.6kPa$ $=0.332atm$

The pressure at sea level is $1atm$ so the pressure at top of the Mount Everest is about one-third of the $1atm$ pressure at sea level.
