When air exerts a force it is called?
-- Pressure -- Wind
How do you know that air exerts pressure?
Because the pressure can be measured with a barometer.
What pressure does cold air exert?
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
How do you calculate satic pressure?
Consists of the pressure the air exerts in the direction of flow (Velocity Pressure) plus the pressure air exerts perpendicular to the plenum or container through which the air moves. (static pressure) In other words: PT = PV + PS PT = Total Pressure PV = Velocity Pressure PS = Static Pressure http://www.refrigeration-engineer.com/forums/archive/index.php/t-14342.html
Why volume of water exerts greater pressure than volume of air?
DENSER MORE PRESSURE PRESSURE PRESSURE LOOK AT SCIENCE TEXT BOOK DONT CHEAT ON WIKI Water has more density than air.
Does heated air produce pressure?
Yes! The heated air molecules always wants to fly upwards because of being lite. We can take the example of a ballon filled with air. When ballon is heated the pressure increases and ballon brusts. This proves that hot air exerts pressure.
When air exerts a force it is called?
-- Pressure -- Wind
Air exerts pressure because it has?
weight
How do you know that air exerts pressure?
Because the pressure can be measured with a barometer.
Dry air exerts less pressure than air that has What?
devin in it
What is exerting pressure?
Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.
How much air pressure exerts in your body?
1 atm
What pressure does cold air exert?
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
Dry air exerts less pressure than air that has?
Dry air exerts less pressure than air that has a higher humidity. In general, air pressure is the sum of the individual pressures of gases present in the air. Dry air lacks any water vapor pressure in the air. Therefore, any air with a humidity above 0% has a higher pressure than dry air.
Cold air exerts more blank than warm air?
air molecules in cold air exert more pressure because they are closer together and collide more often
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
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.
