WebAug 16, 2024 · Therefore, to get to what you were thinking, just use that the number of atoms n relates to the number of oscillators N by n = N / 3. Therefore we have. U = N k T = 3 n k T. Note that this doesn't mean that an Einstein solid has two degrees of freedom like you are proposing the book says. Each 1D oscillator (atom) has 2 ( 6) degrees of freedom. WebEinstein (1907); model a solid as a collection of 3N independent I-D oscillators, all with constant o, and use Planck's equation for energy levels . According to Einstein, the probability f(v) that an oscillator have the frequency v is given by, f(v) = l). Hence the average energy for
