My teacher said it was "internal energy, U" but while in the context of the failures of classical physics in terms of heat capacities. Apparently Einstein calculated the contribution of the oscillation of the atoms to the total molar energy of metal and obtained the quantum equation above in...
Homework Statement
I'm so confused please help :\
Show that the contribution to the total energy from molar internal energy Um reverts to the classical expression at high T.Homework Equations
Classical: Um = 3NakT Quantum Um = 3NAhv/e^(hv/kT)-1
