- Homework 4 For a system of N identical non- interacting particles in a box each having two energy levels 0 and E. Find their fundamental entropy (sigma) and the total energy of the system (U).arrow_forwardConsider a discrete random variable X with 2n+1 symbols xi, i = 1, 2, …, 2n+1. Determine the upper and lower bounds on the entropy when (a) p(x1)=0 (b) p(x1)=1/2arrow_forwardConsider N identical harmonic oscillators (as in the Einstein floor).

- Let Ω be a new thermodynamic potential that is a “natural” function of temperature T, volume V, and the chemical potential μ. Provide a definition of Φ in the form of a Legendre transformation and also write its total differential, or derived fundamental equation, in terms of these natural variables.arrow_forwardNow, let's use this property of logarithms to learn something about the number of microstates available to a molecular system. The absolute entropy of a system is related to the number of microstates available to it via Boltzmann's formula S = kB In W. If a system containing one mole of an ideal gas has an entropy of 167.7 J/K, how many microstates does it have? Report the order of W, as we have defined it above, and you should use scientific notation, 1.23E45, and report 3 (three) significant figures.arrow_forwardConsider again the system of two large, identical Einstein solids. For the case N = 1023 , compute the entropy of this system (in terms of Boltzmann's constant), assuming that all of the microstates are allowed.

If the gas molecules of N molecules cannot be separated from each other, and the partition function ZN of the system is written ZN = Z₁N, the entropy of the gas calculated from Z N is obtained, which is an extensive quantity. 1 O b. If the molecules cannot be separated from each other, the partition function of the system can be written in the form ZN = Z₁N/N!. In this case, the entropy calculated from Z N is obtained, which is an extensive quantity. 1 N O c. If the gas molecules of N molecules cannot be separated from each other, the partition function Z of the system can be written Z N = Z₁N.arrow_forwardLet the system be one mole of argon gas at room temperature and atmospheric pressure.
