john has a barometer for measuring atmospheric pressure as he climbs Mt. Everest. The higher he gets, the pressure reading. Is this a result he should expect?

shamim · Answer

On the mount everest the air pressure will b reduced

shamim · Answer

Air pressire depends on the height of air and density of air

shamim · Answer

On the mount everest both the height and density of air is lower than that of on the earth

mrnood · Answer

The pressure of the air is a result of the weight of the colum of air above you.

In water the pressure is simply rho gh

because water is incompressible and the density remains the same.

With air however the relationship is not so simple because the density of air decreases as you go higher.

However - what IS clear is that there is less air above you when on the top of a mountain than when a lower altitude - therefore the weight of th eair above you is less - therfore the pressure is ...??
