Air Pressure

As the elevation above sea level increase, the corresponding air pressure decrease. A scatterplot comparing elevations, in feet, to air pressure, as a percent of sea level pressure, is shown balow. Q. Air pressure is sometimes measured in inches of mercury. If sea level air pressure measures as 29.2 inches of mercury, what is the approximate difference, in inches of mercury, between the pressure at sea level and the pressure at the death zone threshold?

As the elevation above sea level increase, the corresponding air pressure decrease. A scatterplot comparing elevations, in feet, to air pressure, as a percent of sea level pressure, is shown balow. Q. Elevations above 8,000 meters are said to be in the "death zone", a range of elevations in which oxygen levels are not high enough to sustain human life. What is the approximate air pressure (as a percent of sea level pressure) at the death zone threshold?( Note: 1 meter=3.28 feet)

Does air exerts pressure ?

Describe an experiment to demonstrate that air exerts pressure.

What is atmospheric pressure of air?
