Question

Molecular weight ofor air in sea level is low because

Answer 1

Answer:

At sea level, the density of atmospheric gas molecules is extremely high or highest. Thus, the pressure of air at lower altitude is higherand maximum at sea level. But, as we move upwards, atmospheric pressure decreases due to the lowering of density of gas molecules.

Explanation:

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