What else can I help you with?
The peak of sound wave where the lowest air pressure occurs?
The peak of a sound wave where the lowest air pressure occurs is called the rarefaction. This is the point where the air molecules are spread out, creating a region of decreased pressure compared to the surrounding air.
What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
Where is the lowest access point on a low pressure centrifugal air-conditioning appliance?
The lowest access point on a low-pressure centrifugal air-conditioning appliance is typically at the inlet to the centrifugal impeller. This is where air enters the unit for the cooling process. It is important to ensure proper maintenance and access to this point for inspection and cleaning to maintain the efficiency of the appliance.
Which surface has the lowest friction?
The surface that has the lowest friction is a wet surface, or a surface that has been oiled with light oil, or the air cushion underneath a hovercraft. Then there is the train that runs on magnetic rails, hovering above the rails without physically touching.
How does air pressure move air particles?
Air pressure is the force exerted by the weight of air in the atmosphere. Differences in air pressure cause air particles to move from areas of high pressure to areas of low pressure, in an attempt to equalize the pressure. This movement of air particles creates wind.
Which layer in the atmosphere has the most air pressure?
The layer in the atmosphere that has the most air pressure is the troposphere, which is the lowest layer where most weather phenomena occur. As you go higher in the atmosphere, the air pressure decreases.
What layer of the atmosphere has the lowest pressure?
the exosphere
Why is the air pressure in the troposphere greater with lower elevation?
Air pressure decreases with higher elevation due to the weight of the air column above pushing down. The air at lower elevations has more air above it, creating higher pressure. This is why air pressure decreases as you go higher in the atmosphere.
Which atmospheric layer has the greatest air pressure?
It's the troposphere because :The troposphere contains 75 per cent of the atmosphere's gas. It also holds huge amounts of dust and water vapor, and is often dense with clouds and mist. Air pressure is greatest in the troposphere, because gravity pulls the atmosphere towards the Earth, squeezing most of its weight into this lowest layer.
Which layer of the atmosphere has the lowest air pressure?
http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/layers.html Exosphere That's the outer most layer in the atmosphere. It experiences very low pressures due to the weak gravity at such astronomically high altitudes, and thus the more massive and heavy gases are in levels of the atmosphere, such as the Troposphere.
What is the lowest layer of air?
subsoil
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
What layer is the pressure the highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
Is the crust the layer with the lowest pressure?
yes. Because every other layer is thicker than the crust.
Where is the lowest air pressure typically found within a hurricane?
The lowest air pressure in a hurricane is typically found at the center of the storm, known as the eye.
Which layer of the atmosphere has the least amount of air pressure?
The layer of the atmosphere with the least amount of air pressure is the exosphere, which is the outermost layer of Earth's atmosphere. It is composed of very thin air molecules spread far apart, resulting in extremely low air pressure.
When would the air pressure inside a bicycle tire be lowest?
When you are not sitting on it.
