What else can I help you with?
What happens as you move higher in the tropospere?
Atmospheric pressure falls
What happens to pressure if you increase the ATM?
If you increase the atmospheric pressure, the pressure will also increase. This is because atmospheric pressure is the pressure exerted by the weight of air above a certain point, so increasing the amount of air causes an increase in pressure.
What is the basic instruments for measuring atmospheric pressure?
Atmospheric pressure is measured by a barometer. There are several types. The one most likely to be found in a home is an anaeroid barometer.
What happens when centimeters of mercury are falling?
When centimeters of mercury (cmHg) are falling, it typically indicates a decrease in atmospheric pressure. This can signify an approaching low-pressure system, which is often associated with stormy or unsettled weather. As pressure drops, it can lead to cloud formation, precipitation, and other weather changes. Conversely, rising cmHg indicates increasing pressure and typically clearer, more stable weather conditions.
To change from psig to psia you must add what to p.s.i.g?
You must add the atmospheric pressure.
What happens to atmospheric pressure as altitude increases?
As altitude increases, atmospheric pressure decreases.
When intrapulmonary pressure drops below atmospheric pressure what is able to occur?
When intrapulmonary pressure drops below atmospheric pressure, air rushes into the lungs, causing inhalation or inspiration to occur. This process facilitates the exchange of gases in the alveoli of the lungs, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
What happens to the atmospheric pressure when weather is fair?
it dies
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
What happens as you move higher in the tropospere?
Atmospheric pressure falls
What happens when pressure in the lung is greater than atmospheric pressure?
If the pressure in the lung is greater than atmospheric pressure, air will flow out of the lungs in order to equalize the pressure. This is called exhalation or breathing out.
Why vacuum pressure is negative?
Vacuum pressure is negative because it is measured relative to atmospheric pressure, which is considered the reference point of zero pressure. When the pressure in a system drops below atmospheric pressure and leads to a vacuum, the pressure is expressed as negative to indicate the lower pressure level in comparison to the reference point.
What happens to air pressure when the temperature drops?
When air pressure drops temperature also drops. Thus on high mountains low air pressure is accompanied by low temperature. This is true for high atmosphere also.
What will happens to us if we go seventeen meters underwater?
We will experience a pressure 2.7 times atmospheric pressure.
What happens to pressure if you increase the ATM?
If you increase the atmospheric pressure, the pressure will also increase. This is because atmospheric pressure is the pressure exerted by the weight of air above a certain point, so increasing the amount of air causes an increase in pressure.
What happens when a pressure greater than atmospheric pressure is applied on pure water?
It is compressed and occupies a smaller volume.
What happens with altitude relative to pessure?
as altitude rises less there is less atmospheric pressure
