Specific enthalpy represents the total energy content per unit mass of a substance, taking into account both its internal energy and the energy associated with the work done by or on the substance. It is particularly useful in thermodynamics to analyze energy changes during processes, especially those occurring at constant pressure where the change in enthalpy is directly related to heat transfer.
