Studied by 9 peopleKinetic Molecular Model
Explains the properties of solids and liquids in terms of the following:
Intermolecular forces of attraction
Kinetic energy of the individual particles
Kinetic Energy
the ability to cause changes in matter
Kinetic Energy
it is dependent on the temperature of substance (rise in temperature increases the KE, making particles move more vigorously)
Relationship between kinetic energy and distance between particles
Directly Proportional
London dispersion forces
When two non-polar molecules approach each other, an instantaneous dipole moment forms
London dispersion forces
Weakest type of intermolecular force
Dipole-dipole Forces
only Polar molecules can experience this force
Dipole-dipole Forces
Ex: a slightly negative side of the water molecule is attracted to a slightly positive side of the water molecule
Hydrogen bonds
special type of dipole-dipole
Ion-Dipole Forces
Exists between an ion (charged particle) and a polar molecule
Ion-Dipole Forces
Positive side of the molecule is attracted to the negative ion and the negative side of the molecule is attracted to the positive ion
