Question

What is the mass and weight of air ​

Answer 1

Air is "stuff", as it has molecules that give it mass. Because air has mass, it is pulled down by gravity, and exerts a pressure of about 1 kg/square centimeter (14.7 lbs/square inch)

an object with a mass of 1.0 kilogram weighs approximately 9.81 newtons on the surface of the Earth, which is its mass multiplied by the gravitational field strength.

MASS OF AIR

• Air is "stuff", as it has molecules that give it mass.

• Because air has mass, it is pulled down by gravity, and exerts a pressure of about 1 kg/square centimeter (14.7 lbs/square inch).

WEIGHT OF AIR

• At sea level, on average, the weight of the air above this unit area would weigh 14.7 pounds!

• The pressure applied by this air on the unit area would be 14.7 pounds per square inch.
