The week ahead

Welcome to the 4th week of the course.During this week, we are still talking about the second law of thermodynamics, but we are going be looking at its application to real problems.

To calculate entropy, the third law of thermodynamics is essential. The first law is the energy principle, the second law is the entropy principle. Now, the third law is the temperature principle. The third law leads to a conclusion that absolute zero temperature is never attainable. Based on the properties of entropy and the third law, we are going to solve entropy changes in reversible and irreversible processes.
