By the end
- 01Describe entropy as a measure of how spread out a system's energy is
- 02Explain why an isolated system's entropy never decreases and heads toward equilibrium
- 03Explain how a system's entropy can fall when energy leaves across its boundary
- 04Recognize entropy as a state function, set by the state rather than the history
