Question

what is meant by the term atmospheric pressure pls ans

Answer 1

Atmospheric pressure is the force that the weight of air exerts on a surface.

Answer 2

heya..!!

here is ur ans....

============================

The pressure at the sea level is called 1 Atmosphere pressure. Air pressure decreases as one goes up in height from the sea level.

_________________________

1 Atmosphere = 10 × 10^3 Pa = 1 bar = 10^3 mbar
1 mbar ~ 10^2 Pa (hecto Pascal)

_________________________

Atmosphere pressure is specified in the units mbar or hectopascal (hPa). The atmosphere pressure at a point in air is equal from all sides.

_________________________

If air exists in a closed container, the air molecules in random motion continuously hit the walls of the container. In this interaction a force is exerted on the walls of the container. Pressure is created due to this force.
