|
specific heat C
|
amt of heat needed to raise the temp of 1g of a substance by 1 C or 1K at constent pressure
|
|
|
amut of heat gain (q) =
|
q=MCdT
|
|
|
intermolecular force
|
electrostatic interactions btw different molecule
weaker than ionic and covalent bond dipole-dipole interactions dispersion forces Hydrogen boding |
|
|
strength of intermolecular force
|
H bond>dipole>dispersion
stronger the interaction=higher boiling point |
|
|
Heat of fusion
|
heat require to raise temp to 100 degree
solid melting |
|
|
heat of vaporization
|
liquid boiling
|
|
|
vapor pressure
|
the pressure of the vapor above a fluid due to evaporated molecule
when vapor pressure is equal to the atmospheric pressure, |
|
|
sea level ambient pressure is () so boiling point is ()
|
low
lower |
|
|
sublimation
|

|
fusion/melting
|
solid to liquid
|
|
|
condensation
|

|
liquid to gas
|
|
|
critical temp
|
the highest temperature at which it is possible to convert a gas into liquid
|
|
|
critical pressure
|
the pressure required to bring about liquefaction at the critical temperature
|
|
|
triple point
|
the point at which all three phases are simultaneously present
|
|
|
density of water
|
1g/ml
|
|
|
ex NaCl
posesses an ordered structure, its atoms exist in a specific three dimensional geometric arrangement with repeating pattern of atoms, ions or molecules |
crystalline
|
|
|
ex glass
has no ordered three dimensional arrangement, although the molecules are fixed in place |
