  Ideal gas law - Wikipedia, the free encyclopedia
The ideal gas law is the equation of state of an ideal gas.
The state of an amount of gas is determined by its pressure, volume, and temperature.
The ideal gas law can also be derived from first principles using the kinetic theory of gases, if the molecules are assumed to be hard spheres.

 Ideal gas - Wikipedia, the free encyclopedia
An ideal gas or perfect gas is a hypothetical gas consisting of identical particles of negligible volume, with no intermolecular forces.
The thermodynamic properties of an ideal gas can be described by two equations: The equation of state of a classical ideal gas is given by the ideal gas law.
Any gas behaves as an ideal gas at high enough temperature and low enough density, but at the point where the Sackur-Tetrode equation begins to break down, the gas will begin to behave as a quantum gas, composed of either bosons or fermions.

Ideal gas (or perfect gas) is a hypothetical gas which obeys gas laws exactly.
An ideal gas consists of molecules which occupy negligible space and among which negligible forcess exist (except at collisions).
In such cases, the concept of an ideal gas is extended to that of an ideal Fermi gas or Bose gas.

 Ideal Gas Law   (Site not responding. Last check: 2007-11-07)
An ideal gas is a gas that conforms, in physical behaviour, to a particular, idealized relation between pressure, volume, and temperature called the ideal gas law.
Although no gas has these properties, the behaviour of real gases is described quite closely by the ideal gas law at sufficiently high temperatures and low pressures, when relatively large distances between molecules and their high speeds overcome any interaction.
The ideal gas law may be written in a form applicable to any gas, according to Avogadro's law (q.v.), if the constant specifying the quantity of gas is expressed in terms of the number of molecules of gas.

The volume of a fixed mass of gas is inversely proportional to the pressure at a constant temperature.
Knowing that two ideal gases with the same amount of molecules occupies the same volume and that the total amount of kinetic energy in these two volumes must be the equal, less massive gases will diffuse more rapidly than more massive gases at equal pressure and temperature.
If we know the mass/density and the velocity of a gas, also knowing the mass/density or the velocity of a second gas, we should be able to calculate the velocity or mass/density of the second gas.

 Deviations from Ideal Gas Law Behavior:
Because the volume of the gas particles depends on the number of moles of gas in the container, the term that is subtracted from the real volume of the gas is equal to the number of moles of gas times b.
The ideal gas equation predicts that a plot of PV versus P for a gas would be a horizontal line because PV should be a constant.
According to the ideal gas equation, the pressure would have to be increased to 112 atm to compress 1.00 mol of CO at 0C to a volume of 0.200 L. The van der Waals equation, however, predicts that the pressure will only have to increase to 52.6 atm to achieve the same results.

The Ideal Gas Law reveals that the pressure exerted by a mole of molecules does not depend on what those molecules are, and our earlier observation about gas mixtures is consistent with that conclusion.
