GENERAL KNOWLEDGE

Detailed explanation-1: -In 1873 Johannes van der Waals formulated an equation of state that applies to both gases and liquids. In it he introduced the idea that molecules attract one another to explain why the laws governing gases do not apply under high pressure.

Detailed explanation-2: -Taken individually van-der-Waals interactions are weak attractions between molecules that are in close proximity to each other. They are also known as London dispersion forces.

Detailed explanation-3: -The forces are named for the Dutch physicist Johannes Diderik van der Waals, who in 1873 first postulated these intermolecular forces in developing a theory to account for the properties of real gases.

Detailed explanation-4: -Scientific career His name is also associated with Van der Waals forces (forces between stable molecules), with Van der Waals molecules (small molecular clusters bound by Van der Waals forces), and with Van der Waals radii (sizes of molecules).

Detailed explanation-5: -Johannes Diederik van der Waals, (born Nov. 23, 1837, Leiden, Neth.-died March 9, 1923, Amsterdam), Dutch physicist, winner of the 1910 Nobel Prize for Physics for his research on the gaseous and liquid states of matter. His work made the study of temperatures near absolute zero possible.
