what is the purposes of air and the ideal gas laws

Ideal gas laws are responsible for the working mechanics of airbags.

Ideal Gas Laws and Airbags Another example of ideal gas laws in daily life involve airbags in vehicles. Information on the average pressure in the cabin and the surrounding atmosphere, along with the percentage of oxygen in the atmosphere and the ideal gas laws, indicate how much oxygen is required to maintain the proper equilibrium between the air inside and outside the cabin and keep the air in the cabin fresh. Ideal gas laws are also at work in closed, sealed areas like airplanes where there must be a proper pressure balance between the air inside and outside the aircraft. Buildings with more human activity naturally need more ventilation than buildings where there are fewer people or fewer people moving around. The amount of ventilation that a building needs depends on the number of people in the building and their activity levels. Ventilation units must be installed in any commercial building where air ventilation is not otherwise adequate enough to maintain a balance between the amount of oxygen and carbon dioxide in a building. Ideal Gas Laws in Planes and Buildings One environment where ideal gas laws are useful is in commercial buildings. Although estimations using the ideal gas law are approximate, they are still close enough in many cases. With the exception of some noble gases, such as helium and neon, the ideal gas law is not entirely accurate in describing these relationships. Ideal gas laws demonstrate a relationship between volume, temperature and pressure for a combination of ideal gases.
