Atmospheric Pressure

Atmospheric pressure

Pressure due to the weight of the layer of air acting on the surface of the Earth

Instruments to measure atmospheric pressure

Fortin barometer, Mercury barometer

Applications that use atmospheric pressure

Drinking straw and rubber sucker

Mechanism of syringe

The atmospheric pressure at the surface forces water into the syringe

Mechanism of vacuum cleaner

High atmospheric pressure cause the air to be sucked into the dust bag together with dust

The aneroid barometer is used to measure

Atmospheric pressure
