ideal gas law conditions
low pressure, high temperature
boyle's law
p1v1=p2v2
gases are highly _________
compressible
gases expand ________ to fill the container they are placed in
spontaneously
the distance between molecules in gases are _____
far apart in gases
1 mol of any gas at STP is
22.4 liters
the lighter the gas, _____
the faster the effusion rate
the deviation from ideal behavior of a gas is most evident at high _____ and low _____
pressure, temp
Non reacting gas mixtures are homongeneous
normal melting point at
760 torr or 1 atm
the kinetic-molecular theory predicts that pressure rises as the temperature of a gas
increases because_______
both the gas molecules collide more frequently with the wall and the gas molecules collide more
energetically with the wall
hydrogen bonding
H with N,O,F
isothermal means
at constant temperature
STP
273.15 K and 1 atm
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 boiling point is
1 atm
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 forces?
stronger intermolecular forces between molecules make it more difficult for those molecules to
be pulled apart. Therefore, stronger intermolecular forces result in higher boiling points
solid to liquid
liquid to solid
melting
freezing
liquid to gas
gas to liquid
evaporation
condensation
solid to gas
gas to solid
sublimation
depostition
low vapor pressure
higher surface tension
higher vapor pressure
lower boiling point
large intermolecular forces in a substance are manifested by
low vapor pressure, high boiling points, high heats of fusion, high critical temperatures and
pressures
the stronger the forces between the particles,
the higher the melting point
the higher the boiling point
the lower the vapor pressure
the higher the viscosity
the greater the surface tension
an unsaturated solution is one that
