# Ideal gases

## Equation of state

An ideal gas has the following equation of state:

${\displaystyle pV=\nu RT}$

Where p is pressure, V is volume, ${\displaystyle \nu =m/\mu }$ is number of moles observed, ${\displaystyle R=N_{A}k_{B}=6.022}$ J/(mol·K) is a universal gas constant.

The gas constant has a value of 8.314 J/(mol.K) or 0.0821 (L*atm)/(mol*K)

## Pressure of a gas

let us consider n mole of an ideal gas is placed inside the cubical vessel of side l let the mass of each molecule is m and let it moves with velocity c1
