interactions and energy Self-evident matters? Spreading and spontaneity Particle locations Macroscopic and microscopic states Two independent systems The concept of entropy Gas diffusion Mixing gases Dispersion of energy Energy distribution and entropy Hotter and colder The concept of temperature; the second and third laws of thermodynamics Availability of energy The Boltzmann factor Entropy and free energy Poorly soluble substance Particle positions and energy Evaporation of a liquid drop Balance between entropy and energy; vapor pressure Combustion of magnesium Exothermic reaction with loss of Sconf Burning candle Exothermic reaction with gain in Sconf It gets cold Endothermic reaction Colloidal stability Repulsion driven by entropy What is the driving force?
Total entropy of the system and the surroundings To indirectly keep track of the surroundings The concept of free energy More on gases and the basics of thermodynamics Bike pumps and fridges Gas compression,
pressure and work To work and to heat Definition of work and heat; the first law of thermodynamics To work quickly or slowly Entropy during volume changes; reversible work and the second law The gas follows the law The ideal gas law To heat the kettle Heat capacity The balance of two bank accounts The concept of enthalpy Spontaneity for the most common circumstances The concept of Gibbs energy Mixtures and reactions Take from the bottle and mix Gas mixtures and standard states Can they react?
