1 Comparison of Gases, Liquids and Solids
Property\State Gas Liquid Solid Intermolecular Interaction Virtually none Considerable interaction Flow Fluid – free flow Fluid – nearly free flow Rigid – virtually none Actual/Occupied Volume Ratio Close to Negligible Slightly<1.00 Mode of Motion Virtually random translational motion Restricted translational motion Vibration about fixed sites only Simple Equation of State Yes No

2 Phase Changes

3 Dipole-Dipole Forces Solid and Liquid HCl

4 Ion-Dipole Forces

5 Formation of Induced Dipole in a Helium Atom
No induction in (a), since there are no ions or polar molecules in close proximity. Induction in (b) due to presence of near ion or polar molecule

6 Induced Dipoles in Helium
The induced dipoles exist only momentarily. Nevertheless, at low enough temperatures, the generated dispersion forces are sufficient for helium to condense.

7 Hydrogen Bonds in Water

8 Surface Tension

9 Capillary Action (a) Adhesion is higher (b) Cohesion is higher
