Tues-Day 2
Chem 5 - finished discussing the gas laws in terms of molecular collision frequency and
avg. KE/force of collisions. .
We qualitatively derived Graham's Law of diffusion of gases, and then did a problem with xenon and helium
Tomorrow, finish unit with Graham, avg speed of molecule, Pascal, and Cannizzaro method.
Chem 7/8 - same as 5.
APB - did vertical circular motion question. Ask about net force on mass when mass is on side of vertical circle.
Did banked curve problem; go over banked curve with friction answer tomorrow.
Then finish up unit with various other standard questions, solved with variables.
