The average air pressure at sea level is about 14.7 pounds per square inch (psi), or 101.3 kilopascals. This pressure is caused by the weight of the air in the Earth's atmosphere above us. It decreases as altitude increases.

What is the force exerted by moving air molecules?

The force exerted by moving air molecules is known as air pressure. Air pressure is created by the collisions of air molecules with surfaces and objects in their path. It is this force that allows us to experience the sensation of wind and to measure atmospheric pressure.


What is the difference between air pressure and water pressure, and how do they affect the environment around us?

Air pressure is the force exerted by the atmosphere on objects, while water pressure is the force exerted by water on objects. Air pressure affects weather patterns and can cause winds, while water pressure affects ocean currents and marine life. Both pressures play a crucial role in shaping the environment around us.

Why do one not crushed under the weight of air above us?

The air pressure inside our bodies matches the air pressure outside, so there is equilibrium. Our bodies are also designed to withstand the pressure exerted by the weight of the air above us through structural integrity and the balance of internal and external pressures.


How does barometric pressure vary with altitude?

pressure is a physical unit that measures what we may call the density of force i.e. trhe amount of force exerted on a certain area , the atmosphiric pressure is the force exerted by the air mass on a certain area , clearly more air means more mass , thus , when we go down the air above us increases , and when we go down the amount of air decreases.

Why we don't feel the weight of air on our head?

We don't feel the weight of air on our heads because air pressure is exerted uniformly in all directions, including upwards and downwards. This means that the pressure pushing down on us from the atmosphere is balanced by the pressure exerted by our bodies and the air inside us. Additionally, our bodies are adapted to this constant pressure, making it imperceptible in our daily experience.


IS ambient pressure and atmosperic pressure same?

Yes, ambient pressure and atmospheric pressure can be used interchangeably to refer to the pressure exerted by the Earth's atmosphere at a specific location and time. Both terms describe the pressure exerted by the air surrounding us.


Why does air exert pressure?

Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.

The weight of the air on the earths surface is?

The weight of the air on Earth's surface is approximately 14.7 pounds per square inch (psi), or 101.3 kilopascals (kPa). This pressure is due to the force exerted by the column of air above us, known as atmospheric pressure.


What produces air pressure at the surface of the earth?

Air pressure is the force exerted by the gases in the atmosphere as Earth's gravity pulls on it. The atmosphere can be thought of as a 'sea' of gas surrounding the planet. Air pushes against us from all directions as the weight of air above compresses the air below (this is why altitude affects air pressure.)


What is the downward push of the atmosphere called?

The downward push of the atmosphere is called atmospheric pressure. It is the force exerted by the weight of air above us and is measured in units such as millibars or inches of mercury.

Why is the force exerted on the same amount of area on top of the mountain less than the force exerted at sea level?

Although you didn't mention air pressure, that seems to be what you are asking about. Air exerts pressure because air has weight, and we have a very thick atmosphere (which extends upward for about 200 miles) pressing down on us. But at higher altitudes, such as a mountain top, there is less air pressing down, since only the part of the atmosphere that is higher than where you are, is pressing down on you.
