Question

The pressure atop the world’s highest mountain, Mount Everest, is usually about 33.6 kPa. Convert the pressure to atmospheres. How does the pressure compare with the pressure at sea level?

Answer 1

Answer: 0.33 atm

The pressure at Mount Everest is less as compared to pressure at seal level.

Explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..

All these units of pressure are inter convertible.

We are given:

Pressure atop the world’s highest mountain, Mount Everest = 33.6 kPa mmHg

Converting this unit of pressure into 'atm' by using conversion factor:

1kPa= 0.0099 atm

$33.6kPa=\frac{0.0099}{1}\times 33.6=0.33atm$

Thus the pressure atop the world’s highest mountain, Mount Everest, is 0.33 atm

Standard sea-level pressure is 1 atmosphere.

Thus 0.33 atm at Mount Everest is less than 1 atm at sea level.
