The law of corresponding states is an empirical law encapsulates the finding that the equations of state for many real gases are remarkably similar when they are expressed in terms of reduced temperatures (), pressures, () and volumes (). This law was first described by Johannes Diderik van der Waals in 1913 (Ref. 1).
