The Kinetic Molecular Theory Flashcards
explains the properties of solids and liquids in terms of intermolecular forces of attraction and the kinetic energy of the individual particles.
The Kinetic Molecular Theory
proportional to the temperature, Increased temperature means greater speed.
speed of a particle
hold atoms together in a molecule. It refers to the bond formed with the atom.examples of intramolecular forces:chemical bonds (ionic, covalent and metallic bond)
Intramolecular forces
attractive forces between molecules or particles in the solid or liquid states.They are relatively weaker than the forces within the molecules forming bonds. It refers to the bond formed between molecules.
Intermolecular forces
permanent dipoles that interact with the permanent dipoles of neighboring molecules. The positive end of one permanent dipole of neighboring molecules. The positive end of one permanent dipole is attracted to the negative end of another dipole.
Polar molecules
Attractive forces between an Ion and a polar molecule.
Ion-dipole force
A charged atom or molecule
ION
A negative Ion attracts the positive dipole of another molecule.
A positive ion attracts the negative dipole of another molecule.
Ion-dipole force
Interactions involving induced dipoles. Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces.
Dispersion forces
-The weakest of the intermolecular forces and exists between all types of molecules.
Dispersion forces
The more electrons a molecule has, the stronger the London dispersion forces are.
Dispersion forces
-Since electrons move around a lot, they often are unevenly distributed on an atom or molecule that creates a TEMPORARY dipole moment.(More electrons on one side of atom/molecule means more negatively charged and vice versa) TRue or false
TRUE
is the strongest of the Van der Waal forces. It is a special form of dipole-dipole forces.
Hydrogen bonding
-these intermolecular forces tend to pull the molecules into the liquid and cause the surface to tighten like an elastic film or Skin.
Surface tension
Tendency of a liquid to rise in narrow tubes or be drawn into small openings such as those between grains of a rock.
Capillary action
