particles that are closely together
|
solid
|
|
particles that are close together but not as uniform as solid
|
liquid
|
|
no real structure-- particles are very spread out
|
gas
|
|
the atoms in these solids are arranged in an orderly manner
|
crystalline solid
|
|
no definate shape or volume
|
Gas
|
|
characteristics distinguishing a true solid from other phases of matter
|
particles are vibrating without changing their relative positions
|
|
kenitic theory of gasses
|
energy must be transfered between colliding particles
|
|
ideal gas us made up of gas particles that...
|
are in random motion
|
|
gas at the same temp must have the same
|
average kenitic energy
|
|
gasses occupy different volumes under different conditions of pressure and temp
|
ideal gas behavior
|
|
volume of a gas equals
|
volume of its container
|
|
"elestic"-- particles collide with the walls of their container
|
no kenitic energy lost or gained -- this causes pressure of a gas

diffusion
|
|
at a givenn temp and pressure the GREATER the density of a gas (more massive) the SLOWER a gas effuses
|
Graham's law of effusion (diffusion)
|
|
the passage of a gas (on gasses) through a small opening
|
effusion
|
|
the mixing of two gasses when in contact
|
diffusion
|
|
gasses most likely to behave idealily
|
Hydrogen and hellium
(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
