I.6 Perfect gas

I.6 Perfect gas

This is a theoretical gas model in which, apart from collisions, no account is taken of   interactions between molecules.

PV = n RT

P: pressure (atm, Pa, 1 atm = 1.013 105 Pa, mmHg)

V : volume (L, m³ 1L = 10^-3 m³)

N: number of moles (mol)

R: perfect gas constant (R = 0.0082 L am/mol K = 8.31 J /mol K = 2 cal/mol K)

T : temperature (°C, K, T (K) = T (°C) + 273)
