  Johannes Diderik van der Waals - Wikipedia, the free encyclopedia
Van der Waals was the first to realize the necessity of taking into account the volumes of molecules and the intermolecular forces (now generally called "van der Waals forces") in establishing the relationship between the pressure, volume and temperature of gases and liquids.
Van der Waals was born in Leiden, the Netherlands, as the son of Jacobus van der Waals and Elisabeth van den Burg.
Van der Waals died in Amsterdam in 1923.

Van der Waals is one of the most distinguished men in thermodynamics and author of an equation of state that has become the basis of all modern equations of state and theories of mixtures.
The van der Waals equation of state is discussed in detail with the goal of understanding the reasons for its inadequacy to give a quantitative prediction of the behavior of a real gas.
Van der Waals interactions are observed in noble gasses, which are very stable and tend not to interact, that is why it is difficult to condense them into liquids.

The van der Waals radius of an atom is the radius of an imaginary hard sphere which can be used to model the atom for many purposes.
Van der Waals radii are determined from measurements of atomic spacing between pairs of unbonded atoms in crystals.
The van der Waals radius is named after Johannes Diderik van der Waals, winner of the 1910 Nobel Prize in Physics.

 J. D. van der Waals - Biography
Johannes Diderik van der Waals was born on November 23, 1837 in Leyden, The Netherlands, the son of Jacobus van der Waals and Elisabeth van den Burg.
It was Van der Waals' genius that made him see the necessity of taking into account the volumes of molecules and the intermolecular forces ("Van der Waals forces", as they are now generally called) in establishing the relationship between the pressure, volume and temperature of gases and liquids.
The son, Johannes Diderik Jr., was Professor of Physics at Groningen University 1903-08, and subsequently succeeded his father in the Physics Chair of the University of Amsterdam.

Johannes Diderik Van der Waals (1837-1923) was born in Leiden, the oldest of the ten children of a carpenter.
In the thesis, he introduced the concepts of molecular volume and molecular attraction (presently known as the Van der Waals force), and described the behavior of condensing gases and criticality by means of the famous Van der Waals equation.
Van der Waals was elected to the Royal Netherlands Academy of Arts and Sciences (KNAW) in 1875, and to the Holland Society of Sciences and Humanities (HMW) in 1878.

It had been known for some time that the behavior of real gases differs from that of an ideal gas as predicted by thermodynamics and the kinetic-molecular theory of gases.
Van der Waals was led to the hypothesis of the continuity of the gaseous and liquid states of matter by combining the kinetic theory of gases with Laplace's theory of capillarity.

Van der Waals received the Nobel Prize in Physics in 1910.
In 1908 Van der Waals (Nobel Prize in Physics for 1910) reached the retiring age of 70 and Zeeman was chosen as his successor, at the same time functioning as Director of the Physics Laboratory.
In 1923 a new laboratory, specially erected for him, was put at his disposal, a prominent feature being a concrete block weighing a quarter of a million kilograms, erected free from the floor, as a suitable platform for vibration-free experiments.

This achievement was the consequence of the felicitous collaboration of two Dutch physicists and Nobel prize winners, Johannes Diderik van der Waals (1837-1923) at the University of Amsterdam, and Heike Kamerlingh Onnes (1853-1926) at the University of Leiden.
In 1890, Van der Waals, by generalizing his famous equation of state to fluid mixtures, brought Gibbs’s abstract thermodynamics to practical application.
Van der Waals’ mixture equation inspired a major experimental effort by Kamerlingh Onnes and his collaborators Kuenen, Keesom, and Verschaffelt.

 Van der Waals equation
The Van der Waals equation is an equation of state for a fluid composed of particles that have a non-zero size and a pairwise attractive inter-particle force (such as the Van der Waals force.) It was derived by Johannes Diderik van der Waals in 1873, based on a modification of the ideal gas law.
The derivation of the Van der Waals equation begins with the equation of state of an ideal gas, which is composed of non-interacting point particles:
We now stop treating the fluid's constituent particles as point particles, instead modelling them as hard spheres with a small radius (the Van der Waals radius.) Denoting the volume of each sphere by b, we modify the equation of state to

The development of molecular physics and physical chemistry cannot be understood without a knowledge of the work of Dutch physicist Johannes Diderik van der Waals.
In the years since the end of World War II, there has been a re-appraisal of van der Waals's work, which has established his historic place as one of the founders of molecular science.
This is the only biography of Johannes van der Waals and should be read by anyone with an interest in the history of physics and chemistry, and its most important innovator.
