Enthalpy Changes and Calorimetry

Measuring heat changes in chemical reactions and using Hess's Law to calculate enthalpy indirectly.

Key Questions

  1. 1How can we measure the energy content of a fuel using simple calorimetry?
  2. 2Why is Hess's Law considered a specific application of the Law of Conservation of Energy?
  3. 3How do we account for heat loss in experimental enthalpy determinations?
