42 Cards in this Set

  • Front
  • Back
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
the sum of all pressures of each individual gas in a mixture is equal to the total pressure of the system
dalton's law of partical pressure
the paddage of a gas (on gasses) through a small opening
effusion
the mixing of two gasses when in contact
diffusion

dalton's law of partical pressure
the paddage of a gas (on gasses) through a small opening
effusion
the mixing of two gasses when in contact
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
