eV

(b) At what temperature would the average translational energy of a molecule in an ideal gas be equal to the energy calculated in part (a)?
K Please show all working (a) What is the average energy of a conduction electron in silver at 300 K?
eV

(b) At what temperature would the average translational energy of a molecule in an ideal gas be equal to the energy calculated in part (a)?
K Please show all working

Explanation / Answer

a) Conduction band energy = 5.48 ev

b) 3KT/2 = 5.38 ev

    3KT/2    =5.48*1.6*10^-19 J

    1.5*1.38*10^-23*T = 5.48*1.6*10^-19

                    T =4.2357*10^4 k
