[PAR] [TLE] Van der Waals force [SEP] In physical chemistry, the van der Waals forces, named after Dutch scientist Johannes Diderik van der Waals, are distance-dependent interactions between atoms or molecules.  Unlike ionic or covalent bonds, these attractions are not a result of any chemical electronic bond, and they are comparatively weak and more susceptible to being perturbed.  Van der Waals forces quickly vanish at longer distances between interacting molecules. [PAR] [TLE] Johannes Diderik van der Waals [SEP] Johannes Diderik van der Waals (] ; 23 November 1837 – 8 March 1923) was a Dutch theoretical physicist and thermodynamicist famous for his work on an equation of state for gases and liquids.
