particles that are close together but not as uniform as solid
|
liquid
|
|
|
no real structure-- particles are very spread out

|
|
|
at a givenn temp and pressure the GREATER the density of a gas (more massive) the SLOWER a gas effuses

|
|
|
the passage of a gas (on gasses) through a small opening

(H2) and (He) |
|
|
IDEAL GAS
high temp |
particles move fast
|
|
|
IDEAL GAS
low pressure (high volume) |
keeps molecules far apart and moving fast
|
|
|
IDEAL GAS
small molecules |
minimizes IMFs of attraction
|
|
|
IMFs
|
intermolecular forces
(forces of attraction between neighboring particles) |
|
|
REAL GAS
low temp |
particles move slow
|
|
|
REAL GAS
high pressure (small volume) |
molecules are forced together and attracted to each other
|
|
|
REAL GAS
large molecules |
maximize IMFs
|
|
|
pressure goes up
|
volume decreases
