Question

define atmospheric pressure
​

Answer 1

Answer:

Explanation:

the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).

Answer 2

Answer:

Here is the answer:

• That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
• Atmospheric pressure is commonly measured with a barometer.
• Atmospheric Pressure is the force per unit area exerted on a surface due to the weight of air molecules above it. It is caused by the collisions of the air molecules with that surface.
• We measure atmospheric pressure with a barometer- the height of a column of a mercury indicates the pressure exerted by the air.
• Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface, and is a function of the mass of the planet, the radius of the surface, and the amount and composition of the gases and their vertical distribution in the atmosphere.
