Hi,

I was just wondering the purpose of this question specifying that the orientations in the microstates are of the "same energy"?

`Calculate the entropy of a sample of a solid in which the molecules may be found in any one of three orientations with the same energy. Suppose there are 30 molecules in the sample.`

Why is this important? If the orientations were of different energies, would the Boltzmann formula be invalid?

Thanks!
