thermochemistry
Heat in reactions
Thermochemistry is the branch of chemistry concerned with the heat energy absorbed or released during chemical reactions and changes of state.
It quantifies how much energy is needed to break chemical bonds and how much is released when new bonds form.
Thermochemistry underlies practical applications from designing fuel-efficient engines to understanding why some reactions feel cold to the touch while others generate enough heat to cause burns.
