The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Where is the lowest access point on a low pressure centrifugal air-conditioning appliance?
The evaporator charging valve
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.
What is it called when a layer of warm air is above and traps a layer of cold air below?
Inversion
What effect does cold air have on air pressure?
Cold air increases air pressure
Why is the air pressure in the troposphere greater with lower elevation?
ity is the lowest layer
What is the lowest most dense layer in the atmosphere?
The troposphere, It has the most mass because that is where all the weather occurs.~Amanda~
What layer of the atmosphere has the lowest pressure?
the exosphere
What is the lowest layer of air?
subsoil
What layer is the pressure the highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
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.
Is the crust the layer with the lowest pressure?
yes. Because every other layer is thicker than the crust.
What layer is the atmosphere pressure highest?
The troposphere is the layer of the earth's atmosphere with the highest air pressure.
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.
When would the air pressure inside a bicycle tire be lowest?
When you are not sitting on it.
When the layer of air that surrounds the earth pressed down this is?
Air pressure
When the layer of air that surrounds the Earth presses down this is ?
Air pressure
