the van der Waals equation gas particles have non-zero volumes and interact with each other, molar
volumes of gases of different types are different, the non-zero volumes of gas
particles effectively decrease the amount of "empty" space between them, the
molecular attractions between particles of gas decreases the pressure exerted
by the gas
viscosity is __ the resistance to flow
viscosity increases as temperature decreases, molecular weight increases, intermolecular forces
increase
a volatile liquid is one that readily evaporates
the vapor pressure of any substance at its normal 1 atm
boiling point is
as intermolecular forces increase, vapor pressure ___ decreases
as intermolecular forces increase, normal boiling point increases
___
as intermolecular forces increase, heat of vaporization increases
___
as intermolecular forces increase, surface tension ___ increases
how are boiling points affected by intermolecular stronger intermolecular forces between molecules make it more difficult for
forces? those molecules to be pulled apart. Therefore, stronger intermolecular forces
result in higher boiling points
solid to liquid melting
liquid to solid freezing
liquid to gas evaporation
gas to liquid condensation
solid to gas sublimation
gas to solid depostition
low vapor pressure higher surface tension
higher vapor pressure lower boiling point
large intermolecular forces in a substance are low vapor pressure, high boiling points, high heats of fusion, high critical
manifested by temperatures and pressures
