3.6 Flashcards
real gas behavior
all gases are able to condense ; there are attractive forces
molecules vary in size and have volume
pv does not equal nRT
effect of imfs
as IMFS increase the actual pressure is smaller than the predicted
at higher temperatures IMFS A BECOME NEGLAGBLE AND GASES BEHAVE IDEALY
at low temperatures IMFS come more significant and the gases behvave less idealy
why is pv not NRT
w significant attraction between particles the number of collisions w the walls and particles decrease and the pressure will be less than one atm
decreasing the volume of the container
as volume of the container is less the particle volume becomes more significant , leading to greater pressure
effect of molecular volume
w significant particle volume the space where the particles are free ti move is decreased and the number of collisions with the walls increase and the actual pressure is greater than one
effect of particle volume
as particle volume is more significant , the actual pressure is greater than the actual
at low pressure the space between the molecules is more than the volume of the molecules themselves and the gas behaves more idealy
where as at high pressure the particle volume is significantly reduces the volume in which the particles are free to move and the gas behaves more real
when are gases more real
low temperatures
high pressure
when particles have significant IMFS
when particles have significant molecular size
