Objectives
Introduce the thermodynamic property entropy (S) using the Clausius inequality
Recognize the fact that the entropy is always increasing for an isolated system (or a system plus its surroundings) based on the increase of entropy principle
Analysis of entopy change of a thermodynamic process (how to use thermodynamic table, ideal gas relation)
Property diagrams involving entropy (T-s and h-s diagrams)
Entropy balance: entropy change = entropy transfer + entropy change
