Question:

A general expression for the classical Hamiltonian is:

H = α pi2 + H€²

where pi is the momentum along one dimension for particle i, α is a constant, and H€² are the remaining terms in the Hamiltonian. Substituting this into the equipartition theorem yields:

B(æp} +H')dp³Ndx³N 3N

a. Starting with this expression, isolate the term involving pi and determine its contribution to q.

b. Given that the average energy, Œ©ÎµŒª, is related to the partition function as follows:

(e) %3!

Evaluate the expression for the contribution from pi. Is your result consistent with the equipartition theorem?
