"WebEquation 5.16. ΔH = Hfinal − Hinitial = qp. Just as with Δ E, because enthalpy is a state function, the magnitude of Δ H depends on only the initial and final states of the system, not on the path taken. Most important, the enthalpy change is the same even if the process does not occur at constant pressure. " - How to calculate heat gained by cold water
