The Boltzmann Constant
(e) select and solve problems using the ideal gas
equation expressed as pV = NkT and pV = nRT,
where N is the number of atoms and n is the
number of moles;
(f) explain that the mean translational kinetic
energy of an atom of an ideal gas is directly
proportional to the temperature of the gas in kelvin;
(g) select and apply the equation E = 3/2kT for the
mean translational kinetic energy of atoms.
OUTCOMES
MOST SHOULD
• Understand the difference between R and k and when to apply
them.
• Be able to state that the Boltzmann constant is the gas constant
for a single molecule whilst the molar gas constant is the
constant used when dealing with quantities in moles.
• Be able to explain that the mean translational kinetic energy of
an atom of an ideal gas is directly proportional to the
temperature of the gas in Kelvin.
• Be able to select and apply the equation E = 3/2kT for the mean
translational kinetic energy of atoms correctly in different
situations.
• Be able to select and solve problems using the ideal gas
equation expressed as pV = NkT, where N is the number of
atoms and n is the number of moles.
SOME COULD
• Be able to derive equation for the translational KE of an atom in
an ideal gas E = 3/2kT.
