Entropy - 2nd Law of Thermodynamics - Enthalpy & Microstates

This chemistry video tutorial provides a basic introduction into entropy, enthalpy, and the 2nd law of thermodynamics which states that the entropy change of the universe is always positive for a spontaneous process. It contains plenty of multiple choice practice problems on entropy and enthalpy. Here is a list of topics: 1. Identifying spontaneous processes and nonspontaneous processes 2. Positional Probability & Microstates 3. How To Calculate The Number of Microstates 4. Heads and Tails Probability Example 5. Entropy Description - Disorder vs Order 6. Entropy of the Universe, System, and Surroundings 7. Entropy change of the universe is zero for a reversible process at equilibrium 8. Predicting The Sign of The Entropy of a System Using Heat Flow 9. Positional Entropy of Solids, Liquids, and Gases 10. Relationship Between Entropy and Temperature 11. Relationship Between Entropy, Volume, and Pressure 12. Predicting The Sign of Entropy For Physical Processes - Condensation, Deposition, Freezing, and Sublimation 13. Entropy and Molecular Complexity - Molar Mass of Number of Atoms 14. Predicting The Sign of Entropy For Chemical Reactions 15. Entropy Change Calculations Given Data Table With Standard Entropy Values 17. Entropy Change of Mixing a Solute With a Solvent to Make a Salt Water Solution 18. How To Calculate The Missing Standard Entropy Value of a Compound Given The Standard Entropy Change of a Reaction 19. How To Calculate The Entropy Change of The Universe Given The Enthalpy of Vaporization
