The contents of this video are not required to do your homework, or in-class activities, or the final exam. In this video I discuss the N-molecule energy eigenvalues and summing over all energy eigenstates of the N-molecule system.
I show how the Helmholtz free energy changes as you add more molecules to a box, which allows us to conclude that the internal energy scales in strict proportion to how many molecules are in the box (at a given temperature), but the entropy does not.
