About the Course

Course 3 of Statistical Thermodynamics, Ideal Gases, explores the behavior of systems when intermolecular forces are not important. This done by evaluating the appropriate partition functions for translational, rotational, vibrational and/or electronic motion. We start with pure ideal gases including monatomic, diatomic and polyatomic species. We then discuss both non-reacting and reacting ideal gas mixtures as both have many industrial applications. Computational methods for calculating equilibrium properties are introduced. We also discuss practical sources of ideal gas properties. Interestingly, in addition to normal low density gases, photons and electrons in metals can be described as though they are ideal gases and so we discuss them....

With respect to the previous courses, this was quite simple. The professor's explanation were quite deep and useful.

This is definitely the best course that I've had on ideal gases. It is such an eye opener.

It's really nice to see applied thermo and statistics to this field, but mos of the time it seems quizzes don't relate to the material.

I did not enjoy this course as it contain unwanted quiz numericals and this course is very brief... And not at all able to understand all concepts. It even should contain some solved numericals and a detailed information and explanation.

helps you strengthen your thermo basics and advance further. Excellent course!

The course is good for advanced learners with already some knowledge of radiation, thermodynamics, and quantum mechanics. The exposure to various tools for chemical analysis through this course is good. However, I do feel that the instructor would take his time and teach more elaborately. Also I feel some of the quizzes/discussion prompts arrive earlier than the actual lecture related to it; which seemed a bit odd to me.

The exercises are quite random and several are not doable with the knowledge taught int the course, that's quite frustrating.

This course, the third of the specialization "Statistical Thermodynamics" is dedicated to the ideal gases, where interaction among particles is not considered.

It teaches partition functions for monoatomic and diatomic molecules, i.e., translational, rotational, and vibrational modes, their physical meaning, their use in different contexts, and how to numerically evaluate and plot sets of thermodynamic properties such as specific heat at constant volume, partition functions, and the understanding of the degrees of freedom for molecules composed by several atomic species.

In addition, it gives a nice introduction to the Maxwell-Boltzmann distribution, and asks a set of very interesting problems with numerical evaluation of most of the important quantities

It also teaches the topic of the mixture of gases, an uncommon topic for physicists. It gives some insights into stoichiometric analysis of air and organic molecules, and the different chemical processes, such as combustion, and adiabatic flame temperature.

Finally, it discusses the photon gas, and the electron gas in the context of the Bose-Einstein and Fermi-Dirac Statistics. Several practical examples are discussed in this section as well, that touch from stellar objects such as the Sun to metallic elements such as iron.

I highly recommend this course.

This was a great time , enrolling this course on ideal gases. Thank you Prof. John W. Daily for these course lectures are meant to explain us so beautifully. And thank you Coursera for giving such opportunity.

Again, the concept and lecture of this course are well designed. But unfortunately, the exercise is of relatively poor quality. The assessment is weak as well.
