Answer
Thermochemistry
Explanation
The study of heat changes that accompany chemical reactions and phase changes falls under the domain of thermochemistry. Thermochemistry is a branch of chemistry that deals specifically with the energy and heat associated with chemical reactions and physical transformations. Entropy, Hess's Law, and the Second Law of Thermodynamics are all related concepts within the broader field of thermodynamics, but they do not specifically define the study of heat changes in reactions and phase changes.
