Product Details

Use this set of three thermodynamics demonstrations to both engage your students in a hands-on review and to test their understanding of this sometimes difficult yet fundamental topic.
  • Entropy and Free Energy—Exothermic crystallization of sodium acetate trihydrate sparks a lively debate on spontaneity, free energy, enthalpy, and entropy.
  • Hess’s Law—Two-part calorimetry demonstration provides data for reviewing the properties of state functions and performing H°, ΔS° and ΔG° calculations.
  • Free Energy and Redox Reactions—Solve the Nernst equation for a copper concentration cell to demonstrate the relationship between free energy and electrode potential. 

Concepts: Enthalpy, heat of formation, Hess’s law, calorimetry, entropy, free energy.
Time Required: One class period

Performance Expectations

MS-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
HS-PS1-4. Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
