๐งช Hess's Law: Conservation of Energy in Chemical Processes
Germain Hess proposes Hess's law, an early statement of the law of conservation of energy, which establishes that energy changes in a chemical process depend only on the states of the starting and product materials and not on the specific pathway taken between the two states.โถ
