Il van der Waals equazione è una equazione di stato di un fluido composto di particelle che hanno una non-zero volume e un pairwise attraente inter-particelle forza (come il van der Waals.) È stato derivato da Johannes Diderik van der Waals nel 1873, che ha ricevuto il premio Nobel nel 1910 per 'il suo lavoro sulla equazione di stato per gas e liquidi'. L'equazione è basata su una modifica della legge dei gas perfetti e approssima il comportamento dei fluidi reali, tenendo conto delle dimensioni delle molecole non nullo e l'attrazione tra di loro.
