Pressure of an Ideal Gas
In an ideal gas, molecules have no volume and do not interact.
Pressure of an Ideal Gas formula |

| \(\large{ p = \frac{n \; R \; T_a}{V} }\) | ||
| Symbol | English | Metric |
| \(\large{ p }\) = pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ T_a }\) = absolute temperature | \(\large{R}\) | \(\large{K}\) |
| \(\large{ n }\) = amount of substance | \(\large{dimensionless}\) | |
| \(\large{ R }\) = specific gas constant (gas constant) | \(\large{\frac{ft-lbf}{lbm-R}}\) | \(\large{\frac{J}{kg-K}}\) |
| \(\large{ V }\) = volume | \(\large{ in^3 }\) | \(\large{ mm^3 }\) |
