Van Der Waals Equation Calculator
P = Pressure ; V = Volume ; a , b = Vander waal's Constants ; n= Number of Moles ; R= Universal Gas Constant ; T= Temperature
This online Van der Waals calculator is based on the Van der Waals equation of state. This was derived by modifying the Ideal Gas equation of state. This theory considers that a gas consists spherical particles which have considerable size and takes into account the molecular interaction forces.It is to be noted that for a given value of P, a, b, n, T there exists 3 unique solutions of V (Volume), but only one is shown as the answer here.
