Why does Atmospheric pressure exists because air has what?
Atmospheric pressure exists because air has weight. The weight of the air above exerts a force on the air below it, resulting in pressure at the Earth's surface.
What is the weight of the air pushing down on the earth?
The weight of the air pushing down on Earth's surface is due to air pressure, which averages around 14.7 pounds per square inch (psi) at sea level. This pressure is caused by the force exerted by the weight of the air molecules in the atmosphere above.
Is the weight of the air pressing down on the Earth?
Yes, the weight of the air exerts pressure on the Earth's surface, creating atmospheric pressure. This pressure decreases with altitude as the air becomes less dense.
Weight is the result of air pressure exerted upon an object?
Weight is the force of gravity acting on an object's mass, not air pressure. Air pressure is the force exerted by the atmosphere on objects. Weight depends on the mass of the object and the acceleration due to gravity, while air pressure depends on the density of air and the height above sea level.
What is the weight of the air on the Earth?
The weight of the air on Earth exerts a pressure known as atmospheric pressure, which averages around 14.7 pounds per square inch at sea level. This pressure is created by the weight of the air molecules in the Earth's atmosphere pressing down on the Earth's surface.
How do you calculate weight using specific gravity?
To calculate weight using specific gravity, you multiply the specific gravity of the substance by the weight of the substance in air. This gives you the weight of the substance in a vacuum.
How much hydrogen is enough to lift up 1 kg weight from the ground?
The weight of standard air is 1.2256 Kg/ Cubic Meter The weight of hydrogen is 0.0857 Kg/ Cubic Meter The weight of helium is 0.1691 Kg/ Cubic Meter Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter Subtracting the weight of helium from air gives you the gross buoyant lift of helium as 1.0565 Kg/Cubic Meter These values are variable under altitude, pressure, temperature, humidity and purity of gas. Hope this helps you.
Does the sun gives light and air?
It gives light but not air.
Does air have weight?
Anything with mass has weight; air has mass, therefore it has weight.
What does the weighing machine gives as output. Mass or Weight. What is the common man's mass?
It gives your weight.
Give examples from daily life that air has weight?
air has weight
The weight of air is called?
The weight of air is called atmospheric pressure. It is the force exerted by the weight of the air above a given point in the atmosphere.
What are the 3 properties of air?
The three properties of air are weight, mass, and density.
What is the weight of air on earth is called?
The weight of air on Earth is called atmospheric pressure. It is the force exerted by the weight of air molecules in the Earth's atmosphere on a surface.
Why does the air have mass and weight?
Air has mass because it is composed of molecules, primarily nitrogen and oxygen, which have mass themselves. The weight of air is the result of the gravitational force acting on this mass; when air is contained in a certain volume, the collective weight of all the air molecules contributes to the overall weight. Additionally, air pressure arises from the collisions of these molecules with surfaces, which is a manifestation of air's mass and weight.
How does a flash of lighting affect the air around it?
a. it gives the air a positive charge b.its gives the air a negative charge c.it cools the air d.it warms the air
Why does helium have weight?
Helium has weight because it has mass and is subject to gravity. Despite being much lighter than other elements, helium still has mass and therefore experiences a gravitational force that gives it weight.
