Answer any FIVE Questions.
All questions carry equal marks.
1. Derive expression for vibrational portion function for ideal monoatomic gas.
2. What are the salient features of irreversible process Mentioned the types of irreversibility.
Explain the postulates of irreversible thermodynamics.
3. What is Langranian multipliers Use Langrage method of undetermined multipler. Obtain an
expression for Boltzmann distribution law.
4. Explain, why the values of specific heat molecular hydrogen evaluated by using third law of
thermodynamics.
5. What is classical statistical mechanics How is it related with statistical thermodynamics.
6. Write down Debye theory and derive Debye for evaluation of the atomic heat of solid. How
does D-edye equation explain the variation of specific heat of solid at higher temperature and
lower temperature.
7. How the entropy of a thermodynamics function is related to portion function.
Explain what do you mean irreversible thermodynamics. What are its features and
postulates of irreversible thermodynamics.
8. What is the limitation of Maxwell-Boltzmann static's How are these limitation were overcome
by Bose-Einstein and Fermi Deric static's,
9. Mentioned various types of ensembles. Define canonical ensemble in statistical
thermodynamics.
10. Write short notes on the following
Dulong and Petit's Law.
Liouville Theorem.
