Water (H2O) is being converted from a liquid to a gas. What intermolecular forces must be overcome? What intermolecular force is responsible for the attraction between an ion and a polar molecule? What intermolecular force is very important in humans? What important function...
and Phase Changes11.1a Condensed Phases and Intermolecular ForcesIn Gases (Unit 10), we described the kinetic molecular theory as it applies to gases:●Gases consist of molecules whose separation is much larger than the molecules themselves.●The molecules of a gas are in continuous, random, and...

a(4)Many factors influence van Edward force: molecular size, spatial configuration of molecules, molecular charge distribution. [translate] aH2O is polar molecule ,and O2 is non-polar molecule. [translate] aTherefore ,H2O is larger than O2 in the magnitude of intermolecular forces. [translate] ...
The quantum corrections to the free energy, to order h 2, are obtained for a fluid of rigid interacting molecules in a form suitable for use in computer simulation. The result involves only the mean squared force on a molecule and the components of the mean squared torque about the principal...

The elastic constants computed from the force models show discrepancies from those measured ultrasonically, and these discrepancies are thought to be significant. The long wavelength optical librational frequency measured in the present work differs considerably from that deduced from optical measurements, ...
Two types (one repulsive–attractive and one purely repulsive) of the central‐force potentials, suitable to represent molecule–molecule, atom–molecule and atom–atom interactions, are considered. The expressions for viscosity show good agreement with results of numerical calculations in high‐...
