Van Der Waal Equation

</dt>
The best known of the many laws which have been proposed to describe the thermodynamic behavior of real gases and their departures from the ideal gas laws. It states: [p + (a/v²)](v - b) = RT, where a and b are constants dependent upon the gas; p is the pressure of the gas; v is its specific volume (measured in units of the specific volume of the gas at normal temperature and pressure); R is the universal gas constant; and T is the Kelvin temperature.
