Equation of State: Ideal Gas

The ideal gas equation of state, developed by Benoît Paul Émile Clapeyron (1799-1864 France), is given by:

$pV=N{k}_{B}T$

or

$pV=nRT$

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
