The study of general laws governing the process which involve heat changes, and the conservation of energy is called:
Correct answer: C. Thermodynamics
- A. Thermo chemistry
- B. Conductometry
- C. Thermodynamics
- D. None of the above
Explanation
The correct answer is Thermodynamics. It is a branch of physical science that deals with the relations between heat and other forms of energy, and by extension, the relationships between all forms of energy. It covers the laws of energy conservation and the transformations of energy in physical and chemical processes.Thermochemistry, while related, is specifically concerned with the heat involved in chemical reactions, not all energy changes. Conductometry deals with measuring electrical conductivity, which is unrelated to the question's focus on heat changes and energy conservation. 'None of the above' is incorrect because thermodynamics does address the concepts in the question.

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.
