What is air pressure ?

Question

i need to know what is air pressure i need pic

Answer 1

Air pressure means the pressure exerted by air on any object.

It is force per area ie newton per meter square.

Pressure can be measured by three ways

1. Atmospheric pressure.

2. Very high pressure.

3. Sub atmospheric pressure, Also called as vaccum pressure.

Atmospheric pressure is 1bar and one bar is equal to 1*10^5 newtons.

There is no need of a diagram.

Take an empty plastic bottle and press it at its stomach open and close its cap. You would see a shrink in its size. The sink in its size is dude to air pressure outside the bottle...

Answer 2

air pressure

this is the amount of force forced on you by the column or air above you

this pressure adds up to be an enormous amount that if put on any person would crush them

but because the air molecules push in every direction

the total force is greatly diminished

air pressure is measured with a barometer

as for a pic try google

Answer 3

When you pump air to your car tyre,the air pressure increases.When air leaks,it is called low pressure or flat tyre.

The air column above earth exerts pressure on all .This is called atmospheric pressure. It is about 14.2pounds per square inch or 1 Bar.

You can not have a picture of pressure but can have that of a pressure guage in Goggle.
