|
equilibrium vapor pressure |
pressure exerted by vapor in equilibrium |
|
|
volatile liquids |
evaporate readily |
|
|
molar enthalpy of vaporization |
amt of energy as heart needed to vaporize one moles of liquid at boiling point |
|
|
molar enthaply of fusion |
amt of energy required to melt one mole of solid |
|
|
phase diagram |
pressure vs temperature |
|
|
critical pressure |
lowest pressure substance can exist as liquid |
|
|
kinetic molecular theory |
idea that particles of matter always in motion |
|
|
ideal gas |
perfectly fits all of kinetic-molecular theory |
|
|
elastic collusion |
no net loss of total energy when particles collide |
|
|
laws of kenetic-molecular theory |
tiny particles far apart, elastic collisions, continuous rapid movements, no force of attraction between particles, temp depends on kinetic energy |
|
|
diffusion |
mixing of gas particles evenly across area, opposite is effusion |
|
|
real gas |
does not meet all of kinetic-molecular theory |
|
|
crystalline solids |
crystals, orderly geometric shape |
|
|
amorphous solid |
particles arranged randomly |
|
|
supercooled liquid |
retain liquid properties even when appear to be solid |
