    • 5.1: Energy
      Basic introduction to the concept of energy, with a description of kinetic with respect to chemical entities.
    • 5.2: Heat Capacity
      The heat capacity of a substance describes how its temperature changes as it absorbs heat, it is the capacity of a substance to absorb heat.
    • 5.3: Energy and Phase Transitions
      These temperature goes over heat curves, energy and phase changes.
    • 5.4: First Law of Thermodynamics
      The first law of thermodynamics states that energy can not be created or destroyed, that is, the energy of the universe is constant. This allows us to define a thermodynamic system, which in the case of chemistry is a reaction, with the surroundings being everything else.
    • 5.5: Enthalpy Changes of Chemical Reactions
      Determining the enthalpy of reaction for balanced equations
    • 5.6: Calorimetry
      Applications of the First Law of Thermodynamics to calorimetric calculations involving both real and ideal calorimeters
    • 5.7: Enthalpy Calculations
      Calculating enthalpies of reaction from heats of formation or combustion data, and applying it to real systems.
