Module 11

Kinetic Molecular Theory

• from a Greek word

  meaning to move.

• the behavior of solids in terms of particles in motion.

• the

  behavior of matter in terms of particles in

  motion.

• the size, motion, and energy of gas particles.

Elastic Collision

• far apart, they

  experience no significant attractive or

  repulsive forces.

• one in which no kinetic

  energy is lost.

• small particles separated

  from one another by empty space.

• one is which kinetic energy is lost.

Temperature

• a measure of the average

  kinetic energy of the particles in a sample of

  matter.

• a measure of the highest

  kinetic energy of the particles in a sample of

  matter.

• of a particle depends on mass

  and velocity.

• a measure of the lowest

  kinetic energy of the particles in a sample of

  matter.

Diffusion

• the movement of two material

  through another.

• the movement of three material

  through another.

• the movement of one material

  through another.

• the movement of material

  through another.

Barometer

• equal to a force of one

  Newton per square meter or N/m2.

• demonstrate that air

  exerted pressure.

• measure

  gas pressure in a closed

  container.

• measure atmospheric

  air pressure.

Dispersion Forces

• attractions between

  oppositely charged regions of polar

  molecules.

• weak forces that result

  from temporary shifts in the density of

  electrons in electron clouds.

• special dipole-dipole

  attractions that occur between molecules

  containing

• nonpolar, so relatively weak dispersion

  forces hold the molecule together.

Dipole-Dipole Forces

• weak forces that result

  from temporary shifts in the density of

  electrons in electron clouds.

• highly electronegative atom with at

  least one lone electron pair.

• Ammonia and water both form hydrogen bonds,

• attractions between

  oppositely charged regions of polar

  molecules.

Hydrogen Bonds

• special dipole-dipole

  attractions that occur between molecules

  containing a hydrogen atom bonded to a

  small,

• special dipole-atom

  attractions that occur between molecules

  containing a hydrogen atom bonded to a

  small,

• special dipole-dipole

  attractions that occur between molecules

  containing a hydrogen atom bonded to another

• special

  attractions that occur between molecules

  containing a hydrogen atom bonded to a

  small,

Viscosity

• measure of the resistance of a

  liquid to flow and is determined by the type

  of intermolecular forces, size and temperature.

• measure of the resistance of a

  liquid to flow and is determined by the type

  of intermolecular forces, shape of

  particles, and temperature.

• measure of the resistance of a

  liquid to flow and is determined by the type

  of intermolecular forces.

• measure of the resistance of a

  liquid to flow and is determined by the type

  of intermolecular forces, size and shape of

  particles, and temperature.

Surface Tension

• a measure of the inwards

  pull by particles in the interior.

• energy required to

  increase the surface area of a liquid by a given

  amount.

• compounds that lower the

  surface tension of water.

• compounds that raise the

  surface tension of water.
