AP4 and AP1: reviewed for the test on Monday.
All AP students: I will NOT be in school on Monday.
H8: Pressure and straws (and the failure to drink through a three story straw), Laws and Theories, Kinetic Molecular Theory, Gas laws (Boyle, Gay Lussac, Charles, Foos, Avogadro) and IF problems.
AP1: real life gas stuff (straws, ears, It’s a Wonderful life, snakes on a plane, breathing, Heimlich, wind knocked out, sucking chest wounds, vacuum cleaners, hickeys, hot air balloons and throwing spray paint in the fire.
AP3: reviewed for Monday’s test
AP3 and AP4: LOTS of real life stuff. Review Thursday or Friday (whichever day you have class) Test is Monday.
H8: gas properties, measuring pressure
AP classes: some technical difficulties with the projector today so we went “old school” with the board. I have recreated (simply) the notes we took and they are posted.
Specifically we discussed van der Waal’s equation and some real world stuff (straws, Juicy Juice, three bottle Monty, suction cups, etc)
H8: Boltzmann diagrams and the South Street Effect.
AP4 and AP1: finished Graham’s Law, discussed Dalton’s law (and three types of problems), gas stoich problems and non-ideal behavior.
H8: Charles Law lab (you need to graph length v. Temperature and then use the line of best fit to calculate the temperature at which the length would have been zero).
H8: in class we discussed intermolecular forces, including ion-ion, dipole-dipole, ion-dipole, London Dispersion forces, ion-induced dipole forces, dipole induced dipole forces and hydrogen bonding. We discussed the change in strength of London dispersion forces based on size and on length (surface area) and we ranked the forces from strongest to weakest.
AP1: mole percent oxygen in air lab. Discussed IF problems, PV=nRT, gas density and Graham’s law (please do the Peterson football field problem before Monday’s class).
AP3: Dalton, gas stoich and non-ideal behavior
AP3 and AP4: Mole percent oxygen in air lab (Lab Write up due at 11:59PM to TurnItIn.com next Thursday evening, December 17th). We also discussed IF problems (AP4 only), PV=nRT, gas density and Graham’s Law. I expect answers to the Peterson problem next class.
H8: Test on moles
AP classes: laws (Boyle, Gay Lussac, Charles, Foos, Avogadro) what and why.
AP3: also did IF problems
AP1 and Ap4 also did Kinetic Molecular Theory
H8: reviewed for tomorrow’s test
AP4 and AP1: into to gases, gas properties, measurement of pressure, vacuums and forces
H8: Boyle’s Law lab – graph of P v. V will be used later. Finished moles (calculating molecular formulas and formulas of hydrates) Review tomorrow
AP1: Intermolecular attractions, Boltzmann distributions and the South Street Effect.
AP3: States of matter, properties of gases, units, measuring pressure, straws and barometers, Kinetic Molecular theory
