There are many formula's for calculating the volume of air. The most basic is the ideal gas law. For this law, the answer would be V = R * T / (P * MW), where R = a constant, 10.73, T is the temperature in Rankine, which is Fahrenheit + 459.7, P is the absolute pressure in PSIA, and MW is the molecular weight, in this case use 28.5. The answer will be in cubic feet per pound of air. For example, if I had a container of air and the pressure was reading 10 pounds on the gauge, and the temperature was 70, then the formula would be as follows: PSIA = PSIG + 14.7, so PSIA = 24.7. T = 70 + 459.7, so T = 529.7. V = 10.73 * 529.7 / (24.7 * 28.5). The answer is in cubic feet per pound of air. The volume would be that of its container regardless of pressure.

How are temperature and air mass related?
For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
What happens when you decrease mass in a given volume of air?
The temperature and pressure rise.
The less mass in a given volume of air the what?
greater the air preaser:)
Why is hot air lighter than cold air?
Because its density is lower. At constant pressure, a given volume of hot air thus weighs less than the same volume containing colder air. ---------------------------------------- remark: This can be easily seen from the equation for ideal gases p*V = n*R*T, with p: pressure V: volume n: number of particles within the given volume R: ideal gas constant T: Temperature

A change in can bring about a change in air pressure?
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
How volume of air effects air pressure?
meteorology and water
If the air inside a balloon is heated the volume will?
The volume would increase as the pressure of the expanding air increases.
Why does air pressure decreases when volume increases?
Air pressure is the weight of all the air above you. The higher you go, the more air is below you.
What do air density and air pressure have in common?
At a given temperature, the higher the air density, the higher the air pressure.
What happends to air when its heated?
In accordance with Boyle's Law, if the volume of the air is restricted, the pressure will increase. If there is no volume restriction, the air will expand.
What are 3 factors affect air pressure?
The factors are: -The volume that the air takes up (the greater the volume the less the pressure) -The amount/number of molecules of air (the more gas the higher the pressure) -The temperature (the higher the temperature the higher the pressure) and that's it lol
