Factors that affect the atmospheric pressure are:
(i) Height of air column
(ii) Density of air

Describe a simple experiment to illustrate that air exerts pressure.
Why does a fountain pen leak at high altitude?
At sea level, the atmospheric pressure is 1.04 x 105 Pa. Assuming g = 10 m s-2 and density of air to be uniform and equal to 1.3 kg m-3, find the height of the atmosphere.
Give reasons for the following:
As we go higher, the atmospheric pressure decreases.
Atmospheric pressure at sea level is 76 cm of mercury. Calculate the vertical height of the air column exerting the above pressure. Assume the density of air 1.29 kgm−3 and that of mercury is 13600 kgm−3. Why the height calculated by you is far less than the actual height of the atmosphere?
What is the value of atmospheric pressure?
Give reason:
Air pressure decreases with increasing altitude.
What is meant by atmospheric pressure?
What does low pressure and high pressure lead to?
