  1. you can do it!
  2. Combined gas law
    (P1V1)/(n1T1) = (P2V2)/(n2T2)
  3. boyle's law
    V=1/P
  4. charles's law
    V/T
  5. amontons's law
    P/T
  6. Ideal gas law
    PV=nRT or V={nRT}/{P}
  7. The density of a gas is --------- proportional to its molar mass.
    directly
  8. The density of a gas is ------------- proportional to the temperature
    inversely
  9. Gases mix ------------- in any proportions.Each gas in a mixture behaves as if--------------
    • homogeneously
    • it were the only gas present.
  10. Dalton’s Law of Partial Pressures
    Ptotal = P1 + P2 + P3 +
  11. Postulates of the Kinetic-Molecular Theory
    Postulate 1: Particle Volume
    • Because the volume of an individual gas particle is so small compared to the volume of
    • its container, the gas particles are considered to
    • have mass, but no volume.
  12. Postulates of the Kinetic-Molecular Theory
    Postulate 2: Particle Motion
    • Gas particles are in constant, random, straight-line motion except when they collide with each
    • other or with the container walls.
  13. Postulates of the Kinetic-Molecular Theory
    Postulate 3: Particle Collisions
    Collisions are elastic therefore the total kinetic energy (Ek) of the particles is constant.
  14. If you double the temperature, what happens to the volume?
    A = It doubles
  15. Graham’s Law of Effusion
    The rate of effusion of a gas is inversely related to the square root of its molar mass

    1/sqrt{M}
  16. atm for
    1 Atmosphere
    2 millimeters of mercury
    3 torr
    4 pounds per square inch
    5 Bar
    • 1) 1atm
    • 2) 760 mm Hg
    • 3) 760 torr
    • 4) 14.7 lb/sq in
    • 5) 1.01325 bar
