24. The Second Law of Thermodynamics (cont.) and Entropy

For more information about Professor Shankar’s book based on the lectures from this course, Fundamentals of Physics: Mechanics, Relativity, and Thermodynamics, visit http://bit.ly/1jFIqNu.

Fundamentals of Physics (PHYS 200)

The focus of the lecture is the concept of entropy. Specific examples are given to calculate the entropy change for a number of different processes. Boltzmann’s microscopic formula for entropy is introduced and used to explain irreversibility.
