WebWhat is Enthalpy. The enthalpy is defined to be the sum of the internal energy E plus the product of the pressure p and volume V. In many thermodynamic analyses, the sum of the internal energy U and the product of pressure p and volume V appears. Therefore it is convenient to give the combination a name, enthalpy, and a distinct symbol, H.

WebEnthalpy is heat flow under constant pressure. (qp) Enthalpy is a state function because E, P, and V. are all state functions. If DH gt 0, heat has been gained by the system. from its surroundings endothermic reaction. If DH lt 0, heat has been lost by the system to. the surroundings exothermic reaction. DH is more useful in studying reaction.
