Atmospheric pressure is sometimes defined as the force per unit area exerted against a surface by the weight of air above that surface at any given point in the Earth's atmosphere. In most circumstan...

Air pressure is the force exerted by the weight of a column of air above a particular location. To conceptualize the notion of air pressure, imagine a sealed container full of air as shown in Figure 6.1. When the molecules of air collide with the inside surfaces of the container they exert a pressure.

When you have finished this page, try the Air Pressure Quiz. ... Although they are invisible, the air is filled with tiny molecules. We feel these molecules press against us at times - this is air pressure. Since the molecules in the air are so tiny and are very active and spread out, we do not see them.

Air pressure is the weight of the atmosphere pressing down on the earth. It is measured by a barometer in units called millibars. Most barometers use mercury in a glass column, like a thermometer, to measure the change in air pressure.

At sea level, the weight of the air above this unit area would (on average) weigh 14.7 pounds! That means pressure applied by this air on the unit area would be 14.7 pounds per square inch. Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.

How powerful is air pressure? Can it crush a can? Conduct the experiment below to find out. ... The air pressure decreases as the water vapor condenses inside the can. The can is crushed because the air pressure inside the can is less than the air pressure outside the can.
