= Thermochemistry
{wiki=Thermochemistry}
Thermochemistry is a branch of chemistry that deals with the study of heat changes that occur during chemical reactions and physical transformations. It involves the measurement and understanding of energy changes associated with various processes, particularly focusing on the heat absorbed or released during these processes. Key concepts in thermochemistry include: 1. **Enthalpy (ΔH)**: A measure of the total heat content of a system at constant pressure.
