Relats pressure,volume,tempereture and amount of a gas at any condition. It is a conbination of
*Boyle's law
*Charles law
*Avogadros law
pv=nRT. where r is the proportionality constant also called universal gas constant
R=0.082 L.atom/mol.k
R=8.314 Lkpa/mol.k
R=PV/ RT (1atom)(22.4l)/(1mol)(273k)=0.082 L.atom/mol.k
PV/nT=k P1V1/n1T1=R.

Ideal Gas Law States

The ideal gas law is the equation of state of a hypothetical ideal gas, first stated by Benoît Paul Émile Clapeyron in 1834.

The state of an amount of gas is determined by its pressure, volume, and temperature according to the equation:

where

is the absolute pressure [Pa],
is the volume [m3] of the vessel containing moles of gas,
is the amount of substance of gas [mol],
is the gas constant [8.314 472 m3·Pa·K−1·mol−1],
is the temperature in kelvins [K].
The ideal gas constant (R) depends on the units used in the formula. The value given above, 8.314472, is for the SI units of pascal cubic meters per mole per kelvin, which is equal to joule per mole per kelvin (J mol-1 K-1). Another value for R is 0.082057 L·atm·mol−1·K−1)

R has a different value for each different unit of pressure and the other quantities used. Some values are...

R = 8.314472 m3·Pa·K-1·mol-1
R = 0.08205784 L·atm·K-1·mol-1
R = 62.3637 L·mmHg·K-1·mol-1
R = 10.7316 ft3·psi·°R-1·lb-mol-1
The ideal gas law is the most accurate for monoatomic gases at high temperatures and low pressures. This follows because the law neglects the size of the gas molecules and the intermolecular attractions. Obviously the neglect of molecular size becomes less important for larger volumes, i.e., for lower pressures. The relative importance of intermolecular attractions diminishes with increasing thermal kinetic energy 3kT/2, i.e., with increasing temperatures. The more accurate Van der Waals equation takes into consideration molecular size and attraction. The ideal gas law mathematically follows from statistical mechanics of primitive identical particles (point particles without internal structure) which do not interact, but exchange momentum (and hence kinetic energy) in elastic collisions.

The ideal gas law is a combination of 3 previous laws, those from experiments by Charles, Boyle and Guy-Lussac. It states that PV= kT, where k was a constant. At that time, the concept of a mole was not known, so once it was, the law was modified to PV= n R T, where R is a constant for each measuring system.
