The equation PV=nRT is priceless. I find myself using it in daily life to answer questions about carbination in a warm soda or why a sealed bottle will shrink if you leave it out in the cold. Basically, in a closed environment, according to the forumula, as air pressure decreases, one of many things can happen....The volume V may increase, expanding the bottle. Also, the temperature, T, may decrease. n is the number of molecules in the container, and based on the First Law of Thermodynamics, their number would not change. R is the ideal gas law constant, and as such, remains constant. So again,
(Pressure)(Volume) = (number of molecules)(Constant)(Temperature)

What effect on air pressure with altitude explain briefly?
As altitude increases, air pressure decreases. As altitude decreases, air pressure increases.
What happens to air pressure when density decreases?
density decreases as air pressure increases
As altitude increases air pressure .?
it decreases
What does air pressure do as altitudes?
Air pressure increases as altitude decreases.
Does Air pressure increases as elevation increases?
No. It is a negative correlation which means, as the elevation increases the air pressure decreases.
When the diaphragm contracts the air pressure increases or decreases?
increases
How does altitude affect density and pressure?
Air pressure decreases as altitude increases. As air pressure decreases, so does density.
What decreases as elevation increases?
Air Pressure.
Does air pressure increases with altitude?
no it decreases
What does air pressure do when altitude increases?
Air pressure decreases with increase of height.
What decreases as altitude increases?
the air decreases or wind
Does the pressure inside the bag of balloon increases or decreases?
As the bag of balloon rises, the pressure inside the bag of balloon decreases. Air pressure generally decreases as the altitude increases.
