In this 7-part course, the basics of thermodynamics are discussed in a series of PDF files and Video lectures. The PDF files average 11 pages in outline format and MP4 video lectures average 30 minutes.
PRODUCT OVERVIEW (part 5 of 7):
Why are some thermodynamic processes seen in nature and not others? What determines the flow of heat energy from a hot to a cold object but not the other way around?
In this fifth chapter we introduce the very important concept of Entropy which helps to answer these questions. Through the second and third laws, entropy gives a direction to the flow of processes in the universe (from hot to cold; from order to disorder) and in the process introduces a new phase diagram graph as well as the concept of “free energy” which tells us how much energy in a system is useful for work and how much energy is lost to the environment as waste heat.
Topics covered include:
1. Entropy and the Second Law
2. Clausius, Kelvin-Plank, and Carnot statements of the second law
3. The third law and the Kelvin Temperature scale
4. TS diagrams
5. Helmholtz and Gibbs Free energy
6. Heat Engines
