Ideal Gas Law revisited

•Remember,
the number of molecules contained in one mole of any gas is Avogadro’s
numbers, NA= 6.02 x 1023

•So
*n* = N/NA, where n = no. of moles and N is
the number of molecules in the gas.

•Therefore
PV = nRT= N/NART and

•P
V = N kB T

–kB is *Boltzmann’s Constant*

–kB = R / NA = 1.38 x 10-23 J/ K

–This equation will allow us to
relate the temp. of a gas to the average kinetic energy of particles
in the gas.
