1. The problem statement, all variables and given/known data If the probability of finding a system in any microstate is the same, how can we say there is a most probable distribution energy among the oscillators in the system? 2. Relevant equations None for this particular question. 3. The attempt at a solution Since the interatomic potential energy function provides an accurate description of the electric interactions in solids, which is similar to the potential energy curve of a harmonic oscillator, we can model solids as tiny masses connected by springs. We look at solids because the atoms are in fixed position so we don't have to consider how likely different spatial arrangements might be.
