# Pressure of an Ideal Gas

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

In an ideal gas, molecules have no volume and do not interact.

## Pressure of an Ideal Gas formula

 $$\large{ p = \frac {n \; R \; T_a}{V} }$$

### Where:

$$\large{ p }$$ = pressure

$$\large{ T_a }$$ = absolute temperature

$$\large{ n }$$ = amount of substance

$$\large{ R }$$ = specific gas constant (ideal gas constant)

$$\large{ V }$$ = volume
