The Boltzmann Constant

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.
