AIR PRESSUREi) Understanding Air Pressure

Understanding air pressureKinetic theory of gasses

- tiny moving particles

Why they are moving?.....do you have any idea?

Because of kinetic theory

Gas moving in straight lines until they collide with one another or with wall of container.

Collisions cause the air pressure

Moving all directions…how?

Air pressure around us measured by an instrument called aneroid barometer

Pressure produce by air in the earth’s atmosphere is known as atmospheric pressure

Air pressure decrease when go higher the sea level…why?

Go higher less air..so pressure low at top of mountain
