Thermochemistry

Thermochemistry is the study of heat changes during chemical reactions and physical processes. It helps us understand how energy is absorbed or released when substances react or change state, such as melting or boiling. In classical thermodynamics, we analyze these energy changes through heat, work, and temperature. This knowledge is crucial in fields like chemistry and engineering, as it explains how energy flows and transforms, guiding us in designing efficient processes and understanding natural phenomena. Essentially, thermochemistry connects the energy changes in a reaction to the concept of heat and temperature.
