Unit 5: Thermochemistry

Learning Objectives for Unit 5 is located here.

Feel the heat. During this unit you will be introduced to the relationship between chemical concepts and its counter part, energy. In addition to thermochemistry, there will be an introduction to some thermodynamics which will be picked up also later in the course as needed pre-information is reviewed. Topics to be discussed include: heat, temperature, enthalpy, specific heat, bond length, bond energy, Hess's Law, phase changes, and more.
