Equation of state of ideal gases relating pressure, specific volume, and temperature, i.e., ideal gas law
\(\displaystyle pv = RT \quad \text{where} \quad R = \frac{\bar R}{M}\)
Symbols
- \(p\) — absolute pressure
- \(v\) — specific volume
- \(T\) — thermodynamic temperature
- \(R\) — gas constant
- \(\bar R\) — universal gas constant, 8314 [J/(kmol·K)]
- \(M\) — molar mass
Inputs & Outputs

All properties are computed from the ideal gas law \(pv=RT\). The red dot marks the current state point for the input temperature, pressure, and gas selection. Use the inputs above to move the red dot, or drag it directly on either plot.
