5.1 First Law of Thermodynamics and Enthalpy | General Chemistry

First Law of Thermodynamics and Enthalpy Chad introduces the topic of energy and its units, comprehensively covers the First Law of Thermodynamics, and introduces Enthalpy. First, a basic definition of energy is provided and the Joules, calories, and nutritional Calories are introduced. The First Law of Thermodynamics is then covered both qualitatively and quantitatively as described by the equation: DE = q + w Calculations involving the flow of energy between the system and surroundings through heat and work are explored. Enthalpy is then introduced with a basic definition along with the definitions of Endothermic and Exothermic as types of reactions. An application of enthalpy to stoichiometry (thermochemical stoichiometry) then follows, and the lesson is concluded by describing/defining the six fundamental phase changes and the enthalpy associated with each.
