The virial equation of state is used to describe the behavior of diluted gases. | |||
It is usually written as an expansion of the [[compresiblity factor]], <math> Z </math>, in terms of either the | |||
* | density or the pressure. In the first case: | ||
* | |||
* | :<math> \frac{p V}{N k_B T } = Z = 1 + \sum_{k=2}^{\infty} B_k(T) \rho^{k-1}</math>. | ||
* | |||
* | where | ||
*[[ | |||
*[[ | * <math> p </math> is the pressure | ||
*<math> V </math> is the volume | |||
*<math> N </math> is the number of molecules | |||
*<math> \rho \equiv \frac{N}{V} </math> is the (number) density | |||
*<math> B_k\left( T \right) </math> is called the k-th virial coefficient | |||
