Etymology
Meaning and Origin
Thermochemistry is a branch of chemistry that studies the energy changes that accompany chemical reactions. It deals with the quantitative determination of heat evolved or absorbed during chemical processes.
The term "thermochemistry" was first coined by the French chemist Pierre Duhem in 1882. He used it to describe the study of thermal phenomena in chemical reactions. The term is derived from the Greek words "thermo" (heat) and "chemistry" (the study of matter).
Thermochemistry is a fundamental part of chemistry as it provides information about the thermodynamic properties of chemical substances and the energetics of chemical reactions. It has applications in a wide range of fields, including chemical engineering, materials science, and environmental science.
