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]...
(AMOEBA) polarizable force field and the extended-dipole/induced-dipole (XDID) model as described by Torri48, but modified to include the second hyperpolarizability (Methods). Interestingly, relative to pure water, the ΔΠ(t) amplitude of MgCl2is enhanced, while that of Na2SO4is reduced. ...

(A) Schematic of the single-molecule (+)-strand RNA synthesis assay, showing binding of an RdRp to a hairpin at the 3′ end of the (−)-strand (gray) of the surface-attached RNA construct. A magnetic bead attached to the RNA construct is subject to a constant force of 25 pN durin...
When the wave-function overlap is considerable, the electrons of the hydrogen atoms will be indistinguishable. The total energy will be decreased by the exchange energy, which causes the attractive force. The characteristic property of covalent bonds is a concentration of the electron charge density ...
