Properties of Air at atmospheric pressure

atmospheric pressure Definition Variation Britannica

Atmospheric pressure,also called barometric pressure,force per unit area exerted by an atmospheric column (that is,the entire body of air above the specified area).Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure),which indicates the height of a column of mercury that exactly balances the weight of the column of atmosphere atmospheric pressure Definition Variation BritannicaAtmospheric pressure,also called barometric pressure,force per unit area exerted by an atmospheric column (that is,the entire body of air above the specified area).Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure),which indicates the height of a column of mercury that exactly balances the weight of the column of atmosphere Weather EducationThe Basic Properties of the Atmosphere Pressure.Atmospheric pressure is the force exerted by air on a unit area.It can be thought of simply as the weight of the air above a given point.Simply,the fewer molecules above you,the lower the pressure exerted on you and vice versa (more molecules above = higher pressure).
