Answer:
Hi buddy
Explanation:
YOUR ANSWER IS 4)100KPa
Value of atmospheric pressure at sea level is approx 101.325 kPa (760 mm Hg). This is called 1 atm.
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.
Why is air pressure greatest at sea level?
At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.
