Equation of State: Ideal Gas

Benoit Paul Emile Clapeyron (1799-1864 France)

The Ideal Gas Equation of State is given by:

$\left.pV=Nk_{B}T\right.$

or

$\left.pV=nRT\right.$

where:

• $p$ is the pressure

• $V$ is the volume

• $N$ is the number of molecules

• $n$ is the number of moles

• $T$ is the absolute temperature

• $k_{B}$ is the Boltzmann constant

• $R$ is the Gas constant; $R=N_{A}k_{B}$, with $N_{A}$ being Avogadro constant
