Open ended manometer; Hg column taller than gas
|
pressure of gas = pressure of Hg
|
|
|
Open ended manometer; gas column taller than Hg
|
pressure of gas = 1 atm - press. Hg

|
Closed-ended manomter
|
gas pressure = pressure of Hg

|
Diffusion
|
Rate of spread of a substance throughout a space or another substance.
As the molecules get heavier, diffusion rate decreases |
|
|
Effusion
|
The rate at which a gas leaks out of a small hole in a container.
As the molecules get heaver, effusion rate decreases |
|
|
Ideal Gas
|
Valid only at low pressures
Disregard attractive/repulsive forces between particles Disregard any volume occupied by the particles themselves |
|
|
As pressure increases on a deviant gas, what is the effect on PV/RT?
|
First - drops due to increase in IM forces
Second - rises due to increasing volume of particles |
