WebWhat is Enthalpy? Definition & Meaning Definition of Enthalpy. The sum of internal energy and product of volume and pressure of a thermodynamic system is termed enthalpy. It is a point function (doesn’t depend on the path followed), that’s why enthalpy is a thermodynamic property of a system. In simple words, Enthalpy represents the total ... WebHence, change in enthalpy ∆H = q P, which is the heat absorbed by the system at a constant pressure. In exothermic reactions, heat from the system is lost to the surrounding. For such reactions, ∆H is negative. In endothermic reactions, heat is absorbed by the system from the surroundings. For such reactions, ∆H is positive.
