Atmospheric pressure is the weight of the air above you. this weight is 14.7 lbs per square inch at sea level. Air is made up of 78% Nitrogen - 21% oxygen and 1% trace gasses at sea level, This changes as you ascend as oxygen thins out and other gasses take its place which are lighter than air this changes the partial pressures of the gasses and of cores the weight.
Atmospheric pressure is the force per unit area exerted on a surface by the weight of the air above that surface in Earth's atmosphere. It is commonly measured in units of millibars (mb) or inches of Mercury (inHg). Normal atmospheric pressure at sea level is around 1013.25 millibars or 29.92 inches of mercury.
The atmospheric pressure depends on various factors including the altitude from the sea level. In sea level, the atmospheric pressure is around 760 Hg mm. More informally, this value is also known as 1 atm.

What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
Where on earth is atmospheric pressure greatest?
The atmospheric pressure is greatest at sea level, which is at the Earth's surface. As altitude increases, atmospheric pressure decreases.
What is the symbol for an atmospheric pressure of 1076 millibars and steady?
The symbol for an atmospheric pressure of 1076 millibars and steady is "101076". This would indicate a high atmospheric pressure that is not changing.
What is the physical state of argon at -197 and normal atmospheric pressure?
Argon will be a gas at -197°C and normal atmospheric pressure, as it has a boiling point of -185.8°C at atmospheric pressure.
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
Rain typically occurs in low atmospheric pressure systems where air rises, cools, and condenses to form clouds and precipitation. High atmospheric pressure systems typically bring stable and clear weather conditions with less likelihood of rain.
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
To change from psig to psia you must add what to p.s.i.g?
You must add the atmospheric pressure.
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
Is gauge pressure is the sum of true pressure and atmospheric pressure?
No, it is the DIFFERENCE between the true and atmospheric pressures.
What does absolute pressure include that gauge pressure does not?
abosulute pressure includes the atmospheric pressure while gage pressure gives the pressure above atmospheric pressure
Where on earth is atmospheric pressure greatest?
The atmospheric pressure is greatest at sea level, which is at the Earth's surface. As altitude increases, atmospheric pressure decreases.
What is the Significance of atmospheric pressure?
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
How does one obtain the total pressure of a system that is being operated at the same pressure as current atmospheric pressure?
The total pressure of a system operated at the same pressure as the current atmospheric pressure would be equal to the atmospheric pressure. This is because the atmospheric pressure acts as the external pressure on the system, balancing the internal pressure and leading to a total pressure equivalent to the atmospheric pressure.
What atmospheric pressure causes hurricanes?
Hurricanes form from areas of low atmospheric pressure.
How is the weather linked to atmospheric pressure?
It is linked because if you have high atmospheric pressure it brings blue sunny skies. If you have low atmospheric pressure it bring clouds and rain.
What is the relationship of boiling point with atmospheric pressure?
The boiling point of a substance decreases as the atmospheric pressure decreases. This is because lower atmospheric pressure reduces the pressure pushing down on the liquid, making it easier for the liquid to vaporize. Conversely, higher atmospheric pressure increases the boiling point of a substance as more pressure is needed to overcome the atmospheric pressure and cause the liquid to vaporize.
