A reliable predictor of the behavior of gases and vapors at or near standard atmospheric pressure and temperature and the dilute concentrations encountered in industrial hygiene and air pollution. The ideal gas law is a simplified form of an 'equation of state'. (Calculation Methods - Dinardi p.41)
Volume has to be in Liters, n in Moles and T in degrees Kelvin.
| Variable | Unit |
|---|---|
| P | P = pressure: atm, kPa, mm Hg |
| V | V = volume: Liters |
| n | number of moles |
| R | R = Ideal Gas Constant = 0.0821 (L*atm)/(mol*K) or 8.31441 (L*kPa)/(mol*K) or 62.4 (L*mm Hg)/(mol*K); |
| T | temperature: degrees Kelvin |
