ideal gas

https://doi.org/10.1351/goldbook.I02935
Gas which obeys the equation of state pV=nRT (the ideal gas law; p is the pressure, V the volume, n the amount of molecules, R the gas constant and T the thermodynamic temperature). For an ideal gas the fugacity, f, of each constituent B is equal to its partial pressure, pB, fB=pB=xB p, where xB is the amount fraction of B.
