Ideal gas laws are the parameters that are responsible for the working mechanics of airbags. When airbags deploy, they quickly fill using the right kind of gases to make them inflate and then inflate properly as the vehicle crashes. The ideal gas law states the PV=nRT, where P=pressure, V=volume, n=number of moles of gas, R=the gas constant, and T=temperature.

Ideal gas air

The only interaction between ideal gas molecules would be an elastic collision upon impact with each other or an elastic collision with the walls of the container. [What is an elastic collision?] Properties of Various Ideal Gases (at 300 K) Gas: Formula: Molar Mass: Gas constant: Specific Heat at Const. Press. Specific Heat at Const. Vol. Specific Heat The specific gas constant for dry air is 287.058 J/ (kg·K) in SI units, and 53.35 (ft · lbf)/ (lb · °R) in United States customary and Imperial units. This quantity may vary slightly depending on the molecular composition of air at a particular location. Ideal Gas Law Definition The ideal gases obey the ideal gas law perfectly.

Properties of Air, Ideal Gas . Where: Pr = relative pressure vr = relative specific volume Where Pr and vr are dimensionless quantities used in the analysis of isentropic processes, and should not be confused with the properties pressure and specific volume. Humid Air and the Ideal Gas Law Pressure, temperature and volume for an ideal or perfect gas like air with water vapor - or moist air In a perfect or ideal gas the correlations between pressure, volume, temperature and quantity of gas can be expressed by the Ideal Gas Law. The ideal gas law in terms of R is PmRTV , where P is the absolute pressure of the gas, V is the volume occupied by the gas, m is the mass of the gas, and T is the absolute temperature of the gas. For air in S.I. units, air kJ 8.3143 kmol K kJ J 0.2870 287.0 kg kg K kg K 28.97 kmol R Ru M .
