Air pressure is the weight (not the mass) of the total column of air over a specified area at Earth's surface. It usually measured in kilopascal (about 101 kPa) or mm of Mercury (760 mm Hg). Old style units still in use in America include pounds force per square inch (14.7 psi)
What else can I help you with?
What happens to pressure as the air rises in the troposphere?
Air pressure is simply the weight of the air above you. Air pressure falls with height because the higher you go up, the less air there is above you to weigh down on you.
What is the air density in a hurricane?
The air density in a hurricane is typically lower than normal due to the rising air in the storm's eyewall. This creates a low-pressure center that draws in surrounding air, leading to lower air density compared to the surrounding atmosphere.
When air speed decreases what does air pressure do?
Speed of sound has really nothing to do with atmospheric pressure. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
What uses air pressure to work?
air
What is air moves from a point at which air pressure?
high pressure to low pressure
What happens to pressure as the air rises in the troposphere?
Air pressure is simply the weight of the air above you. Air pressure falls with height because the higher you go up, the less air there is above you to weigh down on you.
Why is a skydiver not really a free fall?
because of air resistance because of air resistance/ pressure
Can you run in the air?
If air pressure is extremely high you could possibly run in the air. So probably at a really high elevation
How much air pressure do you put in the front fork on an 1985 Honda 200x?
Those are actually to let air pressure out that builds up while riding. If you add air to them they will get really stiff.
What is the principle of floatation of an hovercraft?
It floats on an "air cushion", which really just means that there is excess air pressure below it.
Do people really die from lack of air from a hurricane?
No, there is plenty of air (and air pressure) in a hurricane, and plenty of other ways to die in a hurricane.
How are polar and highland similar?
they both have really cold temprature and low air pressure
How is earths air pressure different from seas air pressure?
It is different in that the seas don't have air pressure. No air; no air pressure.
What is the air density in a hurricane?
The air density in a hurricane is typically lower than normal due to the rising air in the storm's eyewall. This creates a low-pressure center that draws in surrounding air, leading to lower air density compared to the surrounding atmosphere.
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
When air speed decreases what does air pressure do?
Speed of sound has really nothing to do with atmospheric pressure. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Why electricity flows better through air if pressure is reduced?
Reducing pressure decreases the density of air molecules, allowing them to move more freely and carry electric charge more effectively. In contrast, higher pressure creates more resistance as air molecules are packed closer together, hindering the flow of electricity.
