| Definition (EN) | gas that deviates from volumetric ideality
Note 1 to entry: No real gas obeys the ideal gas law. Deviations from volumetric ideality can be written in terms of the equation of state
p · V = Z(p,T) · R · T
where:
V is the volume occupied by one mole of the real gas (real molar volume);
Z(p,T) is a variable, often close to unity, and is known as the compression factor (3.10). |

| Definition (BS) | gas koji odstupa od zapreminske idealnosti
Napomena 1 uz termin: Ni jedan realni gas ne poštuje zakon idealnog gasa. Odstupanja od zapreminske idealnosti se mogu zapisati u smislu jednačine stanja
p · V= Z(p,T) · R · T
gdje je:
V zapremina koju zauzima jedan mol realnog gasa (realna molarna zapremina);
Z(p,T) promjenljiva, često blizu jedinice, a poznata je kao faktor stišljivosti (tačka 3.10). |
