Chemical reactions involve a change in heat energy and the study is called?
Correct answer: C. Thermochemistry
- A. Electrochemistry
- B. Biochemistry
- C. Thermochemistry
- D. Analytical Chemistry
Explanation
Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling. A reaction may release or absorb energy, and a phase change may do the same.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
