decreases.
7. PSI decreases 1 PSI every _, _ _ _ ft.
2,343 ft <<<< higher you go less psi.
8. Gases are compressible, then liquids are?
Liquids are considered incompressible.
9. an area containing pressure below atmospheric pressure.
Vacuum
10. What is the reason why a container that has less pressure inside than outside?
Negative Pressure (Vacuum) : Result the can will crumple.
