Use the Gibbs distribution to calculate thermodynamic properties (including entropy, all relevant thermodynamic potentials, and heat capacity), of an ensemble of similar two-level systems, in thermodynamic equilibrium at temperature T that is comparable with the energy gap (delta). For each variable, sketch its temperature dependence, and find its asymptotic values (or trends) in the low- temperature and high-temperature limits.

Also, calculate the probabilities of the energy level occupation, and give physical interpretations of your results, in both temperature limits.

Use the microcanonical distribution to calculate thermodynamic properties (including entropy, all relevant thermodynamic potentials, and heat capacity), of an ensemble of similar two-level systems, in thermodynamic equilibrium at temperature T that is comparable with the energy gap (delta). For each variable, sketch its temperature dependence, and find its asymptotic values (or trends) in the low- temperature and high-temperature limits. Hint: The two-level system is generally defined as any system with just two relevant states whose energies, say E0 and E1,...

Calculate the enthalpy, entropy, and Gibbs free energy of mixing when 1.00 mol hexane is mixed with 1.00 mol heptane at 298 K. You may treat this solution as ideal. Sketch the plot of entropy of mixing vs. mole fraction, and then sketch another plot for entropy vs. mass fraction. Calculate the mass fractions of hexane and heptane that would provide the greatest entropy of mixing.
