John has a barometer for measuring atmospheric pressure as he climbs Mt. Everest . the higher he get the higher the pressure reading . is this a result he should except ?
A : Yes atmospheric pressure and height are related
B : No , there is no pressure from air on Mt. Everest
C : No atmospheric decrease with height
D : Yes , pressure increase with height and elevation ****
Hey, hang on ! THINK!!!
The gravitational field of earth pulls the air molecules toward the center of earth,
just like it pulls water molecules in the ocean toward the center.
As a result, as you go toward the center of earth, either in air or in water, you get more and more weight above you and the pressure goes UP UP UP.
THEREFORE atmospheric pressure DECREASES with height, and is zero once you reach space.
Therefore his barometer was BROKEN.
yes atmospheric pressure and height are related
D: Yes, pressure increases with height and elevation.
Explanation:
As John climbs Mt. Everest, he will experience a decrease in atmospheric pressure. This is because atmospheric pressure decreases with increasing altitude. The barometer measures the pressure exerted by the weight of the air above it, so as John climbs higher, there is less air above him and therefore less pressure. Therefore, John should observe a decrease in pressure readings as he climbs higher on Mt. Everest.
