Date :Définition
The branch of chemistry that embraces the determination and study of the heat absorbed or evolved in the formation and dissociation of compounds in chemical reactions and in changes of phase (liquid to vapor, solid to liquid, etc.).
Note :
This information is essential in chemical engineering, for the heat or energy balance of a reaction is directly related to the design of large-scale equipment, such as heat-exchangers, distillation and fractionation towers, evaporators, and the like. Application of these data involves knowledge of the three laws of thermodynamics.
