15,1 kinetic theory
mole SI unit for the amount of substance
Definition the amount of substance that
contains as many elementary entities as there
are atoms in 0.012 kg of carbon 12
Avogadro constant no of particles in
one mole of a substance
Symbol NA
value 6,02 1023
N Na n
1 no of
miles
Birtities infate
m n x M
mate Mtiest mma's
the antie of a substance
, kinetic theory for an ideal gas
The gas contains a large no of molecules atoms
moving in rand m direction in random speeds
The molecules atoms occupy a negligible volume
compared to the volume of the gas
lollisions of molecules atoms with eash other and
the container walls are perfectly elastic
time of collisions between molecules atoms
is
negligible compared to the time between collisions
electrostatic forces between molecules atoms are
negligible except during collisions
