Misconceptions Stability and Change Entropy is a measure of disorder. Learning Outcomes Energy and Matter The second law will bring the world to “heat Scale, Proportion, and Quantity death “, namely thermal equilibrium in Recognize why the second law of which no energy will flow. thermodynamics requires two bodies at Any system could be 99.99% efficient different temperatures for work to be done. Any system can be run reversibly Calculate the efficiency of a heat engine. Internal energy and enthalpy are Relate the disorder of a system to its ability to interchangeable do work or transfer energy as heat. Steady state and equilibrium are Phenomenon interchangeable terms. Factors which impact how quickly a reaction occurs also impact how much product is created.
