No. The pressure changes depending on elevation and also the current weather.
About 1013 millibars would equal about... 30 inches------------_______________*****************
This is because the air inside the balloon is a fairly high pressure than the atmospheric pressure air outside the balloon. On the other hand air pressure inside the glass bottle is already equal to the atmospheric pressure so it is difficult to remove air from a glass bottle.
They are called isobars.
It will fill the area of lower pressure, expanding and slightly cooling until the pressure of the area and it's surrounding are equal.
1: the pressure on a surface at which a flowing fluid is brought to rest in excess of the pressure on it when the fluid is not flowing2: the quantity of air measured by most airspeed instruments and equal to the product 1⁄2 ρV2 where ρ is the density of the air and V is the relative speed of the air
Air pressure, everywhere, varies day to day dependant on weather factors
No - that's why we get winds. Winds are caused by air flowing from high-pressure areas to low-pressure zones. AVERAGE atmospheric pressure at ground level is 14 psi. (pounds per square inch)
Yes. Everywhere on the surface of the earth has air pressure except for artificially created vacuum chambers. The air pressure in a tornado is lower than the pressure in its surroundings.
In an open system the vapor pressure is equal to the outside air pressure.
Yes it is equal
Yes
There is no difference of the average local air pressure inside or outside of the headphone.

ounce(s) per square inch.
no they are equal
air pressure is not always the same everywhere, areas with different air pressure can cause changes in the weather. These areas may have lower or higher air pressure then their surroundings
