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
solid to gas
deposition
gas to solid
freezing
liquid to solid
fusion/melting
solid to liquid
condensation
gas to liquid
vaporization
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
amorphous
two common form of crystaals
metallic and ionic crystal
