Question

What is atmospheric pressure at sea level?​

Answer 1

Answer:

Explanation:

Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

Answer 2

Answer:

Pressure decrease with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevation, there are fewer air molecules above a given surface than a similar surface at lower level.
