It occurs between neutral atoms and molecules.", "Image ImageDescription": "The explanation of these weak forces of attraction is that there are natural fluctuation in the electron density of all molecules and these cause small temporary dipoles within the molecules. It is these temporary dipoles that attract one molecule to another. They are called van der Waals forces. The bigger a molecule is, the easier it is to polarise (to form a dipole), and so the van der Waal s forces get stronger, so bigger molecules exist as liquids or solids rather than gases.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
