Hess's Law of Constant Heat Summation: The standard enthalpy of a reaction, which takes place in several steps, is the sum of the standard enthalpies of intermediate reactions into which the overall reactions may be divided at the same temperature.
$Δ H = Δ H_{1} + Δ H_{2} + Δ H_{3}$
It is applicable to determine heat of formation, transition, reaction, hydration, etc.
