## What is the approximate mass of a column of air 1 cm?

CONCLUSION: 2 The weight of a column of air with 1 cm area is 10.1 N and the mass is 1.030 kg.

## What is the mass of a column of air that has a cross sectional area of 1 square centimeter and that extends from sea level to the top of the atmosphere?

What is the mass of a cubic meter of air at 20 celsius at sea level? What is the mas of a column of air that has a cross sectional area of 1 square centimeter and that extends from sea level to the top of the atmosphere? about 1 kg. What is the weight of this air column?

What is the pressure at the bottom of the column of air referred to in the preceding question?

What is the pressure at the bottom of the column of air referred to in the previous question? atmospheric pressure equals the pressure under 10.3 m of water and so it can’t push water higher.

### What is the mass of a cubic meter of air at room temperature 20 C )?

At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft3.

### What did the Magdeburg sphere prove?

The Magdeburg hemispheres are a pair of large copper hemispheres, with mating rims. They were used to demonstrate the power of atmospheric pressure. The hemispheres became popular in physics lectures as an illustration of the strength of air pressure, and are still used in education.

What is the weight of the air column in the area of 1 cm 2?

On average, a column of air with a cross-sectional area of 1 square centimetre (cm2), measured from mean (average) sea level to the top of Earth’s atmosphere, has a mass of about 1.03 kilogram and exerts a force or “weight” of about 10.1 newtons, resulting in a pressure of 10.1 N/cm2 or 101 kN/m2 (101 kilopascals, kPa) …

#### What is the atmospheric pressure at sea level over an area of 1 square centimeter?

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.

#### How much does pressure drop with altitude?

Since more than half of the atmosphere’s molecules are located below an altitude of 5.5 km, atmospheric pressure decreases roughly 50% (to around 500 mb) within the lowest 5.5 km. Above 5.5 km, the pressure continues to decrease but at an increasingly slower rate.
