What is atmospheric pressure from absolute pressure?
Pressure can be defines as a force acting normally on unit area of the surface. also mathematically pressure can be defined as : pressure= normal force/ area Atmospheric pressure decreases with altitude and is measured by barometer. ...

When cold air moves into an area the atmospheric pressure is?
When cold air moves into an area, the atmospheric pressure is high because cold air is denser than warm air. When a cold front moves through an area, the pressure always rises. ...
What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure?
As air pressure in an area increases, the density of the gas particles in that area decreases. ...
Where does the force of a cyclone come from?
Cyclone is caused due to the variation of atmospheric pressure in the air. Especially in the low atmospheric zone, air comes from all sides to balance the atmospheric pressure in that area. That's why cyclone is created. So the force for cyclone comes from variation in atmospheric pressure. ...
Asked in Chemistry
How do you increase pressure and decrease pressure?
Pressure is force divided by area. To increase pressure, you either make the force bigger or the area smaller To decrease pressure you either make the force smaller or the area bigger Hope this helped From the Biology Lesson Ravesses ...
Asked in Meteorology and Weather
Why does the wind blow when there are clouds but not when it is sunny?
The statement is not true. Wind is the product of atmospheric pressure systems. Clouds present only within a certain area of the atmospheric pressure system. ...

Why does atmospheric pressure change as you go up in altitude?
Atmospheric pressure is basically the weight of the column of air above you, go higher and the column is shorter resulting in less weight over the same area (lower pressure) ...
Asked in Clouds
Give two examples on how area affects the pressure?
area affects pressure ,for example like when you walk on sand while wearing heels or flat shoes ,the area of heel is smaller so larger is the pressure whereas area of flat shoes is larger so smaller the pressure. ...
What is a device that displays atmospheric pressure?
A barometer. Barometric pressure is usually read and rated in millibars of atmospheric pressure. A standard day at sea level, would be 29.9 on the barometric scale. That is, neither a high or low pressure in the area and generally sunny. ...

The force on an area from the push of air?
We know that force acting perpendicularly on an area is thrust & thrust acting on an unit area is called pressure. Pressure exerted by wind or air hasn't been classified individually,rather we all together say it atmospheric pressure. And it is nearly 100000 Pa. so we may say it as atmospheric pressure. -----Akashraj Ghosh, Kharagpur ...

The measure of the force with which air molecules are pushing on the Earth's surface?
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi") ...
