Why Thermodynamics?
Why Thermodynamics?
Changes in a substance’s properties or change into a different substance require an exchange of energy. Chemical systems undergo three main processes that change their energy: heating/cooling, phase transitions, and chemical reactions.

The study of thermodynamics - the driving force behind chemical reactions - accounts for 10-15% of the AP Chemistry Exam.
